The class of the objectclassName = class(obj)obj = MyClass with properties: Property1: 10 Property2: 20className = 'MyClass'>> isobject() function in MATLABThe isobject() function in MATLAB is used to determine if a variable is an object of a user-defined class. This can be particularly useful when you need to check the type of a variable before performing operations that are specific to objects.In MATLAB, variables can belong to different data types, including numeric arrays, character arrays, structures, cell arrays, and objects. An object in MATLAB is an instance of a class, which can be either a built-in class or a user-defined class. The isobject function helps to identify if a given variable is an object.Syntaxtf = isobject(A)In the syntax above.A − The variable you want to test.tf − A logical value (true or false). It returns true if A is an object; otherwise, it returns false.Let us see few examplesExample 1: Checking a Numeric ArrayA = [1, 2, 3, 4, 5];tf = isobject(A);disp(['Is A an object? ', num2str(tf)]);In the example above tf = isobject(A); checks if A is an object.On execution in matlab command window the output is −>> A = [1, 2, 3, 4, 5];tf = isobject(A);disp(['Is A an object? ', num2str(tf)]);Is A an object? 0>>Example 2: Checking a StructureThe code we have isB = struct('field1', 10, 'field2', 20);tf = isobject(B);disp(['Is B an object? ', num2str(tf)]);Here tf = isobject(B); checks if B is an object.On execution in matlab command window the output is −>> B = struct('field1', 10, 'field2', 20);tf = isobject(B);disp(['Is B an object? ', num2str(tf)]);Is B an object? 0>> Example 3: Checking a User-Defined ObjectFirst, define a custom class MyClass in a file named MyClass.m:The code we have is.% MyClass.mclassdef MyClass properties Property1 Property2 end methods function obj = MyClass(val1, val2) obj.Property1 = val1; obj.Property2 = val2; end MATLAB is a very powerful, high-level technical computing language used by mathematicians, scientists and engineers to solve problems in a wide range of application areas.

Download 1.0.0.0 6 Nov 2013 Download Variables in the workspace that are symbolic variables.The syms command is a convenient shorthand for the sym syntax, and its typical use is to create fresh symbolic variables for interactive symbolic workflows. Use the sym syntax to create the following:Symbolic variables in MATLAB functionsMany numbered symbolic variablesSymbolic variable whose value differs from its name in the MATLAB workspaceSymbolic number, such as sym(3)/11Symbolic variable that inherits the assumptions from a previously used symbolic variable having the same nameCreate Symbolic ExpressionsSuppose you want to use a symbolic variable to represent the golden ratio φ= 1+ 52.Use sym to create the golden ratio.phi = (1 + sqrt(sym(5)))/2;Now you can perform various mathematical operations on phi. For example:Next, suppose you want to study the quadratic function f=ax2+bx+c. First, create the symbolic variables a, b, c, and x.Then, create a symbolic expression f that represents the arithmetical expression ax2+bx+c.Solve the quadratic equation f=0 for x by using solve.x_0 = (-b+b2-4 a c2 a-b-b2-4 a c2 a)You can also apply a mathematical function to an arithmetical expression. For example, apply the Bessel function of the first kind J0 to the arithmetical expression f and find its derivative with respect to x.DJ_0 = -Jbesselj1(a x2+b x+c) b+2 a xTo create a symbolic number in a symbolic expression, use sym. Do not use syms to create a symbolic expression that is a constant. For example, to create an expression whose value is 5, enter f = sym(5). The command f = 5 does not define f as a symbolic expression.You can also create symbolic expressions from strings by using str2sym when reading expressions from text files or when specifying numbers exactly.Reuse Names of Symbolic ObjectsIf you set a variable equal to a symbolic expression and then apply the syms command to the variable, MATLAB removes the previously defined expression from the variable.For example, create a symbolic expression f.If you recreate f, then MATLAB removes the value a+b from the expression f.You can use the syms command to clear variables of definitions that you previously assigned to them in your MATLAB session. syms clears the assumptions of the variables.

– Create numbered symbolic variables, symbolic variables in MATLAB functions, or symbolic numbers whose values differ from their names in the MATLAB workspace.syms – Create fresh symbolic variables for interactive symbolic workflows, that is, for symbolic variable creation at the MATLAB command line or in MATLAB live scripts. A fresh symbolic variable does not have any assumptions.The syms command is shorthand for the sym syntax, but the two functions handle assumptions differently. syms clears the assumptions when creating variables. However, recreating a variable using sym does not clear its assumptions. For more details about the differences of these two functions, see Choose syms or sym Function.Create the symbolic variables x and y using syms and sym, respectively.The first command creates a symbolic variable x in the MATLAB workspace with the value x assigned to the variable x. The second command creates a symbolic variable y with the value y.With syms, you can create multiple variables in one command. Create the variables a, b, and c.Create Array of Symbolic VariablesIf you want to create a MATLAB array of numbered symbolic variables, you can use the sym or the syms syntax.Use sym to create an array of many numbered symbolic variables. Clear the workspace. Create a row vector containing the symbolic variables a1,…,a10 and assign it to the MATLAB variable A. Display the variable in the MATLAB workspace.clearA = sym("a",[1 10])A = (a1a2a3a4a5a6a7a8a9a10) Name Size Bytes Class Attributes A 1x10 8 sym A is a 1-by-10 array of 10 automatically generated elements. These generated elements of A do not appear in the MATLAB workspace.Use syms to create many fresh symbolic variables with corresponding variable names in the MATLAB workspace. Clear the workspace. Create the fresh symbolic variables a1, ..., a10. Display the variables in the MATLAB workspace. Name Size Bytes Class Attributes a 1x10 8 sym a1 1x1 8 sym a10 1x1 8 sym a2 1x1 8 sym a3 1x1 8 sym a4 1x1 8 sym a5 1x1 8 sym a6 1x1 8 sym a7 1x1 8 sym a8 1x1 8 sym a9 1x1 8 sym The MATLAB workspace contains 10 MATLAB

MATLAB® has two ways of calling functions, called function syntax and command syntax. This page discusses the differences between these syntax formats and how to avoid common mistakes associated with command syntax.For introductory information on calling functions, see Calling Functions. For information related to defining functions, see Create Functions in Files.Command Syntax and Function SyntaxIn MATLAB, these statements are equivalent:load durer.mat % Command syntaxload('durer.mat') % Function syntaxThis equivalence is sometimes referred to as command-function duality.All functions support this standard function syntax:[output1, ..., outputM] = functionName(input1, ..., inputN)In function syntax, inputs can be data, variables, and even MATLAB expressions. If an input is data, such as the numeric value 2 or the string array ["a" "b" "c"], MATLAB passes it to the function as-is. If an input is a variable MATLAB will pass the value assigned to it. If an input is an expression, like 2+2 or sin(2*pi), MATLAB evaluates it first, and passes the result to the function. If the functions has outputs, you can assign them to variables as shown in the example syntax above.Command syntax is simpler but more limited. To use it, separate inputs with spaces rather than commas, and do not enclose them in parentheses. functionName input1 ... inputNWith command syntax, MATLAB passes all inputs as character vectors (that is, as if they were enclosed in single quotation marks) and does not assign outputs to user defined variables. If the function returns an output, it is assigned to the ans variable. To pass a data type
