Matrix product expression and evaluation #8

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Add expression classes and corresponding evaluators to support matrix-matrix, 
matrix-column, row-matrix products.

- The evaluator should be based on template BLAS wrappers
- uniform syntax (compile-time dispatch under the hood)

    C = mm(A, B);

Additionally, it should evaluate the following expressions in an efficient way:

    C = scalar * mm(A, B);
    C = mm(A, B) * scalar;

    C += scalar * mm(A, B); 
    C += mm(A, B) * scalar;

Directly use destination with simple alias detection.
