I need an example of a defined function in M-files

Help me on how to define functions

[Jan]

Such questions are explained exhaustively in the "Getting Started" chapters of the documentation. Reading this is obligatory, when you want to use such a powerful tool as Matlab.

I will try your suggestion

Answer 1

[Walter Roberson]

Put the following into a file named example.m :

function example
  disp('You rang?')
end

Then, invoke it by typing

example

at the command prompt.

It is important that the file name be a .m file that has the same name as the first "function" being defined in the file.

Answer 2

[Matt Fig]

1. From the command line, type this: edit
2. Copy the code below.
3. Paste it into the blank window that opened from step 1.
4. Save the file, use the name MATLAB gives it.
5. From the command line, type this: mysquare(2)

function y = mysquare(x)
% mysquare(x) squares the input argument.
y = x.^2;
