hi everybody Today I have a question about Kronecker products, If you have a direct answer it is perfect but if not, any kind of paper reference might work as well. now say I have to matrices A and B in general there is nothing special about them. They are not hermitian or triangular or what...

Hi I found solution to my problem, let me share it in case someone else might need it; lets assume C=A*B and A, B, C are matrices with dimensions $$ A_{(m,n)}, B_{(n,k)}, C_{(m,k)} $$ Assume we are trying to find A for given B and C Then the number of equations we have is m*k, one...

Hi everybody I have a question that I have a guess for the answer but I want to be sure I have an identity C=A*B where A,B,C are matrices and in general they are not square is there a way to find A in terms of B and C by using pseudo inverse matrix or using pseudo inverse might help me in...

Hi everybody I finally understand the problem, I will put a note to here in case someone else might need it A and B are matrices n is a natural number say ##AB-BA=\phi## then we will have ##(AB)^2=ABAB## which is equal to ##A(AB-\phi)B## then we get ##=AABB-A\phi B## finally...

Hi guys I have a problem in finding my error in a calculation, I will be glad if you help me to find the error that I am doing ok the problem is basically about matrix exponentials, here we go: A, B, U, P are matrices n is a natural number t and T are rational numbers and T=n*t now in...

Hi to everybody I am a student in physics department of M.E.T.U (Middle East Technical University). I am also a member of Metu Physics Socity a group of people want us (From the physics Society) to make a domno show for an international fair opening. We thought to make a show with nearly...
