My RHSvec is a 51X21 matrix. kdpolind is 11X51X21. Doing the following:
[RHSval,kprimeind] = max(RHSvec,[],2);
gives me a 51X1 RHSval and a 51X1 kprimeind.
if kprimeind is as follows:
16
20
20
16
20
16
16
then I want to store in kprimeind in kdpolind as
kdpolind(act,1,16)
kdpolind(act,2,20)
kdpolind(act,3,20)
kdpolind(act,4,16)...
I am unable to do this due to dimensions mismatch. Is there a simple way of doing this?
Thanks!

[RHSval,kprimeind] = max(RHSvec,[],2,'linear');
kdpolind(act,kprimeind)= vector_that_is_51x1
