Hi,
I have a function named sample as follows:
function x= sample(*func_f*)
It takes in input another function which is to be processed. Now in another matlab file, I access all the files in one directory (which are functions) and i need to pass them into this sample function.
I use the following approach for this:
T=dir(['./' fcts_folder '/*.m']);
funcname=T(i).name(1:end-2);
x= sample( str2func(funcname) )
But this gives me an error : Undefined function 'sample' for input arguments of type 'function_handle'.
Any ideas how I should go about this?

no I am in the directory where sample.m is and the functions that I need to pass are in the fcts folder in a directory inside the directory where sample.m is.

"no I am in the directory where sample.m is and the functions that I need to pass are in the fcts folder in a directory inside the directory where sample.m is."
That would likely be your problem. The functions in the fcts directory need to be in your path. Add them with addpath or pathtool

No the problem isn't this. This thing I have taken care of, checking files in a subdirectory.
I solved the problem. I wasn't making an object of the class in which this sample function was. Once I made the object and then called the function it worked.
Thanks a lot for your help though ! I appreciate it.
