# MATLAB: How to optimize this matlab code

vectorization

I am new to matlab and trying to optimize this matlab code through optimization
function X = DWT2DCT(x,Dct_matrix,W_matrix)[M,N,K]=size(x);y = zeros(K,M*N);X = zeros(K,M*N);temp = zeros(M,N);for k=1:K     temp = W_matrix*x(:,:,k)*W_matrix';     y(k,:)=temp(:)';endX = Dct_matrix*y;
Till now I explored that it is possible through vectorization and this loop can be vectorized can someone please guide me

y = reshape(multiprod(multiprod(W_matrix, x), W_matrix'), [], K)';
