    ® provides a large number of functions that perform computational tasks. Functions are equivalent to subroutines or methods in other programming languages.

    To call a function, such as , enclose its input arguments in parentheses:

    A = [1 3 5];
    max(A)
    ans = 5
    

    If there are multiple input arguments, them with commas:

    B = [10 6 4];
    max(A,B)
    ans = 1×3 10 6 5

    Return output from a function by assigning it to a variable:

    maxA = max(A)
    maxA = 5
    

    When there are multiple output arguments, enclose them in square brackets:

    [maxA,location] = max(A)
    maxA = 5
    
    location = 3
    

    Enclose any character inputs in single quotes:

    disp('hello world')
    hello world
    

    To call a function that does not require any inputs and does not return any outputs, type only the function name:

    The clc function clears the Command Window
