???Error using feval Undefined function 'pfpower' for input arguments of type 'double'.???
显示 更早的评论
Hi everybody
I was trying to understand previous answers to similar questions as mine indcated in Question subject above, but I didn't get it.
I'm using Matlab R2012a and I'm trying to run the function below from Hadi Saadat textbook, but the first error that I get is:
Error using feval Undefined function 'pfpower' for input arguments of type 'double'.
Could you please give me any hint ? it's because the function was developed in another Matlab version.
Thanks in advance for your help

could you please insert your function as such? ( use the {}Code option ) It is not easy to follow what's a comment and what's code.

It's Ok, if the fucntion is written in the earlier version. Pls. make sure the script (m file) which defines the function is in current folder or has been added to Matlab path.
