I have the following m file:

function [Data] = calc_file(u)

where I would like to enter u as a vector. When I try to do this I get the following error:

 >> calc_file(u)
 ??? Undefined function or method 'calc_file' for input
arguments of type 'double'.

How do I enter a vector as the input for a function?

You need to post the code for calc_file.

From your question, you seem to get this error only when u is a vector and not when it is a scalar?

It looks like the calc_file.m is not on your path.

I only get this error when i use a vector, with scalars it runs fine. And yes the calc_file.m is in my path.

OK, could you post the code in calc_file.m?
