Linear algebra multiplication. For 2D matrices: matmul. For 2D×1D: mat-vec. For 1D×1D vectors: element-wise. Scalar broadcasting supported.

Name	Description
a	Left operand (NDArray or scalar)
b	Right operand (NDArray or scalar)

NDArray result

>> mul([2, 3], [4, 5])

[8, 15] (1D element-wise)

>> mul(reshape([1,0,0,1], 2, 2), reshape([2,3,4,5], 2, 2))
