WebWe are multiplying Matrices, not scalars. Matrix multiplication is NOT commutative. If A and B are matrices such that AB and BA are defined (can be multiplied) AB≠BA. Check the … WebWe may define multiplication of a matrix by a scalar mathematically as: If A = [aij]m × n is a matrix and k is a scalar, then kA is another matrix obtained by multiplying each …
WebUpdate: Here's a short explanation for the code.The main idea is to turn the given lists into one-hot-encoded: a b c d 0 1 1 1 0 1 0 1 1 1 2 1 1 1 0 3 1 1 1 0 . Once ... WebCDMA encoding is obtained as, X1 = S*DM where S is the signature matrix of size NxN and the size of X1 is NxM. The near-far effect is implemented by taking the near-far coefficients randomly in the range 0.85 to 1.15 (a spread of 15 percent) and forming the near-far matrix as, A = 0.01*randi([85,115],N,M) (5)
