* |
Binary multiply, Forms the product of two operands |

Special operators are defined to designate conventional matrix and array operations.
Operator |
Action |
** |
Binary MATRIX multiply. Forms the product of two matrices or the product of a MATRIX and an ARRAY. Applied to tensors, the result is the same as the DOT operator. |
// |
Matrix "division". A1 = A2 // M produces the ARRAY A1 satisfying the equation A2 = M**A1. |
