- you could arrange so that F and T_h1 either have the same size or else have sizes that are suitable for implicit expansion
- you could pad F or T_h1 to be the same size as the other before doing the calculation
- you could give up on that calculation and do something else
Question: is it possible that the number of rows of F is the same as the number of columns of T_h1, or the number of columns of F is the same as the number of rows of T_h1, but the arrays are not square and not equal size? If so then perhaps what is wanted is
G = F .* T_h1';
which is the conjugate transpose operator applied to T_h1, not the conjugate operator.
