Web9 mrt. 2024 · Solution actually is pretty simple: Transpose the k-vector and compare with both other vectors using implicit Cartesian expansions, giving logical arrays of sizes and . Now just transpose the -matrix and multiply, killing the k-dimension. Not quite used to matrix multiplication with logical arrays, but it makes a lot of sense here. Web12 mei 2024 · For matrix multiplication, you take two matrices and your final answer is another matrix (or a row vector (1xn matrix) or a column vector (nx1 matrix)), but for this you need the number of columns of your first matrix to equal the number of rows of your second matrix because that's how matrix multiplication was defined.
