Nettet9. mar. 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.
