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.

WebNov 6, 2024 · 2 First thing, if you want to do matrix multiplication use numpy.matmul or the @ operator, e.g. B@A. Also, when you define A like A = np.array ( [ [1], [0]]) this creates a 2x1 vector (not 1x2). So if you want to multiply the vector A with the matrix B (2x2) this should be C = B*A, where C will be a 2x1 vector C = B@A WebYou can only multiply matrices in which the number of columns in the first matrix matches with the number of rows in the second matrix.
