y = a * b
where a and b are arrays of numerical type. The result y depends
on which of the following three situations applies to the arguments
a and b:
a is a scalar, b is an arbitrary n-dimensional numerical array, in which case the output is the element-wise product of b with the scalar a.
b is a scalar, a is an arbitrary n-dimensional numerical array, in which case the output is the element-wise product of a with the scalar b.
a,b are conformant matrices, i.e., a is of size M x K, and b is of size K x N, in which case the output is of size M x N and is the matrix product of a, and b.
a and b are integers, the output is an integer also, while in the third case if a and b are integers, ,the output is of type double.
and the second form
In the third form, the output is the matrix product of the arguments
--> a = [1,3,4;0,2,1] a = 1 3 4 0 2 1 --> b = a * 2 b = 2 6 8 0 4 2 --> quit
The matrix form, where the first argument is 2 x 3, and the
second argument is 3 x 1, so that the product is size
2 x 1.
--> a = [1,2,0;4,2,3] a = 1 2 0 4 2 3 --> b = [5;3;1] b = 5 3 1 --> c = a*b c = 11 29 --> quit
Note that the output is double precision.
