Multiplying matrices (article) | Matrices | خان اکیڈیمی
A matrix is a rectangular arrangement of numbers into rows and columns. Each number in a matrix is referred to as a matrix element or entry.
Transposes of sums and inverses - Khan Academy
I think it's pretty obvious that (cA)^T = c(A)^T, so we can represent transposing a matrix as a linear transformation, and therefore a matrix product. I guess my question is, how do we construct the matrix that will transform any matrix A to its transpose A^T?
