mul method
Performs an element-wise multiplication or division of the two matrices.
The method returns a temporary object encoding per-element array multiplication, with optional scale. Note that this is not a matrix multiplication that corresponds to a simpler "*" operator.

Implementation
Mat mul(Mat other, {bool inplace = false, double scale = 1.0}) {
final p = inplace ? ptr : calloc<cvg.Mat>();
cvRun(() => cffi.Mat_Mul(ref, other.ref, p, scale));
return inplace ? this : Mat._(p);
}
