You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fmt_cassi.m
    path of file: ./repos/3DCS/utils
    
    the code of the file until where you have to start completion: function [ fy ] = fmt_cassi( H,y )
%FMT_CASSI Forward model of the coded aperture snapshot spectral imager 

    
function [ fy ] = fmt_cassi( H,y )
%FMT_CASSI Forward model of the coded aperture snapshot spectral imager 
%(CASSI).
%   fy=FMT_CASSI(H,y) returns the result of  transpose of the measurement 
%   matrix multiplies the measurement vector, that is fy=H.*y, 
%   where H is Nx-by-Ny-by-Nt matrix denoting the code or patterns of the 
%   imager, f is the original 3D sample with the same dimensions as H.
%   See also FM_CASSI.
fy  = bsxfun(@times,H,y);
