Scalar and matrix multiplication
WebFeb 15, 2024 · More Answers (2) You can use the .* operator to perform element-wise multiplication between a matrix and a scalar. For example, to multiply each element of matrix p1 by a scalar value 100, you can write: This will create a new matrix with the same dimensions as A, where each element of p1 is multiplied by 100. WebApr 23, 2024 · large_dimension = 1000 a = np.random.random ( (1,)) b = np.random.random ( (1, large_dimension)) c = np.matmul (a, b) In other words, multiplying matrix b with the scalar a [0]. I am looking for the most efficient way to compute this, since this operation is repeated millions of times.

WebSep 30, 2015 · EDIT The question is this: Scalar multiplication is defined as B = A * s, where B and A are equally sized matrices (2D array of numbers, in this example let's use integers) and s is a scalar value. Each element of A is multiplied to s, which is then stored in the corresponding element in matrix B.
