Keywords like break, case, catch, class, continue, else, etc. Keywords cannot be used as variable name.(Built-in function like cos, sin, exp, sqrt, etc.). MATLAB Built-in function cannot be used as variable name.So the function call would be HandleVariable( 'VarNameStr', VarValue, 'VarFile. No spaces are allowed between characters. I would prefer passing the variable name as a string (VarNameStr) in this case and convert it to a variable name inside the function.For example, AA, Aa, aA, and aa are the names of four different variables. MATLAB is case sensitive: it discriminates between uppercase and lowercase letters.Punctuation characters (e.g., period, comma, semicolon) are not allowed for defining variable names.A variable name can be made with letters, digits, and the underscore character.Variable name length limits up to 63 characters long.A variable name must start with a letter.fprintf(‘The x is %d The y is %d The r is %d ’,x,y,r) statement to display variables x, y and z.10, 32 and -12 are the values assign to variables x, y, and z respectively.Output The x is 10 The y is 32 The r is -12 The statement in MATLAB is given by x = 10 y = 32 r = -12 įprintf('The x is %d The y is %d The r is %d ',x,y,r) We can assign values to multiple variable in single statement. fprintf(‘The x is %d ’,x) statement to display variable x value.

In MATLB, fprintf statement is used to print a variable data. fprintf(‘%s ’,x) statement used to print variable x data.Hello is the string assign to variable x.The statement in MATLAB is given by x='Hello' fprintf(‘%d ’,x) statement used to print variable x value.Īn assignment statement used for assigning the string to a variable.

10 is the value assigned to variable x.

The statement in MATLAB is given as x=10 The assignment statement generally having the symbol = which is known as the assignment operator. Assign the value to a VariableĪn assignment statement used for assigning a value to a variable. In MATLAB, an assignment statement automatically generates variable. However, they remain a string and thus i cannot use it with the interp1 command.After reading this MATLAB Variable topic, you will understand how to create and manipulate Variable, and you will understand how to assign and display variable data in MATLAB. These are now stored in the variables interpvec1 and interpvec1 respectively. Inflex_Ratio = interp1(interpvec1,interpvec1,Sweep,'linear') įor example: I want to create the variable X5(:,1) and X5(:,2). This concerns the following piece of code: WingType = strcat(Airfoiltype,TwistType) Ĭase 'UncamberedUntwisted' %%. Hence, my question is: how do I change a string to a variable within the frame of MATLAB? However, it is still classified as a string and therfore I cannot use it in my while loop. This string is actually the name of a variable. Within a loop, I am creating a string by using strcat. I am working on a Matlab script and I am running in the following problem:

String to variable name matlab
