Cant run a function

Hi

I am only 3 days old in the MATLAb so please excuse my naiveness.

I am trying to write a very basic function to get a homogeneous matrix. however when i try to run it or to call the function in the cmd line i get the error saying 'error in practice1(line 3). Doesnt say what the problem is. I have defined the function in 'practice.m' and intend to call it using 'practice1.m' or directly in the cmd line.

What am i doing wrong here?

You must define one function in a single file and save it in the name of the function.

function x = rot1(p)
% define your formula
end

Save the above in the name rot1.m. When you call it, just call by the name of function. Like below:

p = pi/4 ;   % your value
x = rot1(p) ;

Thank you! that worked!

Does this mean that If i want to define 'n' functions, i have to create 'n' different files per function?

If you want to have access from outside, yes you need to have n files for n functions. If you want to have access in a single main function, then you can define all the functions in a single main function.
