How can solve the error is Undefined function 'size8cut' for input arguments of type 'uint8'.

Hello, can anyone help me with the following problem matlab:

I have the function:

function Y=size8cut(X) % cut the rim of the image, to make it more fit to be cut into 256*256 patches
  [m,n] = size(X);
  if mod(m,8)~=0
      X=X(1:m-mod(m,8),:);
  end
  if mod(n,8)~=0
      X=X(:,1:n-mod(n,8));
  end
  Y=X;
end

the error is

   Undefined function 'size8cut' for input arguments of type 'uint8'.

If anyone knows how to solve the problem, please I need to solve it urgent.

Thank

[Jan]

Do not post the question as a comment in addition. I recommend to avoid the term "urgent" carefully. The users of this forum are volunteers and nobody wants to be pushed.

When you write a function m-file, you need to save it as a .m file on your search path.

Do NOT put it in the MATLAB toolbox directories. MATLAB does not look there for new functions.

help addpath
help savepath

which size8cut -all

I am already saved at .m and put it inside my current directory.but still the error.

when write the following

help addpath
help savepath

which size8cut -all

C:\Users\ismail\Desktop\QA_release\QA_release\size8cut.m

Note: A simplification:

function X = size8cut(X)
% cut the rim of the image, to make it more fit to be cut into 256*256 patches
[m, n] = size(X);
X      = X(1:m-mod(m,8), 1:n-mod(n,8));
end

How are you invoking your size8cut function? If you are invoking it from within other code, then it is possible that the other code is changing directories (or even the path) so that size8cut can no longer be found. Try adding your directory C:\Users\ismail\Desktop\QA_release\QA_release specifically to the MATLAB path instead of relying on it being found in the current directory.
