sir,this is the 4D matrix=
T=[A1 0 0 0;A2 A1 0 0;0 A2 A1 0; 0 0 A2 A1] where
A1=[qn'p00 qn'p01 p10 p11] and
A2=[qnp00 qnp01 0 0]; and the column vector is 2(QHn(t)+1)-dimensional column vector of ones. here the size of the column vector changes with respect to time. I want to multiply this matrix with the column vector . I don't know how to multiply.Can you please help me sir?
