make function in matlba in matlab

To create a function in MATLAB, you can follow the syntax:

function [out1, out2, ...] = functionName(in1, in2, ...)
    % Function body
end
81 chars
4 lines

Here, functionName is the name of the function, in1, in2, ... are the input arguments, and out1, out2, ... are the output arguments. The function body contains the code that performs the desired computations and assignments.

For example, let's create a function that squares a given input:

function square = mySquare(x)
    % Compute the square of x
    square = x^2;
end

5 lines

Here, mySquare is the name of our function and x is the input argument. Inside the function body, we calculate the square of x and then assign it to the square variable. We can call this function from the command window or from another MATLAB script or function:

main.m
>> y = mySquare(5)
y =
    25
