You have given us no information about the size() of each of the variables involved.

You are not giving us info to debug this directly. But I can give you some advice on how to debug it.
When you have a long line of code like this, try to separately evaluate small segments. Remove sections until the code runs, and then add them back in one-by-one. Try to isolate the piece that makes this break, in a systematic fashion.

Mariam, We don't know the values for any of your variables, so we cannot reproduce the error. Can you put the full script please?
On a side note: you are switching between element and matrix multiplication (the dot ".") .* is element wise multiplication. * is matrix multiplication. I suggest you check that.
