i have a loop that every time insert a vector in one row of a matrix but when i assign it i give this error massage :Index exceeds matrix dimensions. this is my code for assigning :
ps{psize,pcol}=cl{1,pcol};
that psize is 500 and pcol is 15

Please give the entire error message, that means ALL the red text, not just some of it. I want to know if it's failing at the very last, lower right element of each, in other words
ps{500,15} = cl{1,15};
or if you're trying to assign some other elements, like cl{2,42} or something. The error message should say how many elements there are in the arrays.

Check the sizes of ps and cl, and check if they are not less than pcol and psize

At the MATLAB command line, give the command
dbstop if error
and run the program. When it stops, examine
size(cl)
pcol
I suspect you will see cl being smaller than you expect.
Question: why not use
ps(psize, pcol) = cl(1, pcol);
That would be less internal work. This will not make a difference to the array index error you are getting, but it is generally safer.
