i am unable to concatenate to my desirable length. y1 is of dimension 16x99, y2 is of dimension 16x99, y_in and y_qd must be of dimension 16x396 but i am getting it as a 1x6336 during concatenation .
help in concatenation of the matrix will be appreciated
help me in this regards

Why don't you post the entire error message for us and we can see if we can help.

if i am using the reshape the error message is this
Error using reshape
Product of known dimensions, 16, not divisible into total number of elements, 99.
if i am not using the reshape then there will be no error but it will compute the matrix of dimensions for y_in = 1x6336 , y_qd=1x6336, , ymod and ycomplex =1x6336
