WebSince we want the determinant to be nonzero for the gradients to be linearly independent, we need to solve the equation: 72(x1 + x2 + x3)(x1^2 + x2^2 + x3^2) - 36(x1 + x2 + x3) - 12x1x2x3 + 3 ≠ 0. Unfortunately, this equation is difficult to solve analytically, and we will need to resort to numerical methods or approximations. WebJul 16, 2016 · Multiplication of two matrices m 1 × n 1 and m 2 × n 2 is possible if either: m 1 = n 2 (i.e. nrow of 1st matrix = ncol of 2nd matrix) n 1 = m 2 (i.e. ncol of 1st matrix = nrow of 2nd matrix) The resulting matrix always has: m 1 …
