DonAntonio, HallsofIvy and AlephZero, Thanks for your comments and help. As I was discussing my problem with a mathematician, he advised me to use the "Tensor Product" instead and after a quick survey, looks like that I can use a special case of tensor product, called "Kronecker product"...

Thanks for your reply, Chiro. Some are diagonal and some are not. For one case I have reached from: [A]8x2.[B]2x2.[C]2x4.[D]4x1.[E]2x8 to: []8x1.[]2x8 which obviously are not compatible for matrix multiplication. These are populated as follows: A = [A11 0 0 A22...

Dear members, I have a rather silly question. As we all know only the compatible matrices can be multiplied. My derivation of some Finite Element formulation has, however, led me to the multiplication of two incompatible matrices. I was wondering if we could make these incompatible...
