A= eye(3,3)
B= eye(6,6)
kron(A,A) resulting in 9x9 identity matrix, how to change the dimension of 9x9 matrix into 6x6 matrix using voight system in matlab.
Cep=k*kron(A,A)+2*(B-1/3*(kron(A,A)))

Hi,
kron function returns kronecker tensor product of two matrices therefore size of resulting matrix will be [size(A,1)*size(B,1) size(A,2)*size(B,2)] for two matrices A and B. So, you may check if only a sub part of the matrix is required or B matrix can be different.
