I have four 4x4 matricies called: ox, ru, cr, po.
I have been successful in using the Kronecker tensor product for two of the matricies, I being a 4x4 identity matrix.
mat = kron(I,ox) + kron(ru,I);
However, when I try doing the same with all four matricies...
mat = kron(I,I,I,ox) + kron(I,I,ru,I) + kron(I,cr,I,I) + kron(po,I,I,I);
I get an error saying 'Too many input arguments.'
Is here a way to achieve the result for four matricies?
