Undefined operator '-' for input arguments of type 'cell'

Smoothed_XY is a cell array of n number of rows and 2 columns. All what it cotains are double variables.

I try to run this line:

xd = (Smoothed_XY{i,1}(3:end,1) - Smoothed_XY{i,1}(1:end-2,1)) / (2*Ds) ;

where i is a counter in a loop.

It runs without any problem in a single code, but when it is in a function part of another code, this error appears:

"Undefined operator '-' for input arguments of type 'cell'".

Yes, it seems silly, but that what I find.

Hi Hazem,

Just looking at your provided one command line, only intuitive concern might be with an improper call function name or location of your set sub- or nested fucntions. Without looking at your whole code, it is a bit difficult to say any solid points.
