 <a id="details" name="details"></a>## Detailed Description

coefficient wise access to [Matrix](class_matrix.xhtml "Standard matrix class. ")

This class provides operators and functions for coefficient wise access for matrices, i.e. it provides a scalar view on all matrix elements.

Operators cover elementwise scalar operations. Functions cover a wide field of scalar functions applied to all elements.

By using a reference counting system it is guaranteed that the refered object will not be deleted before the [MatrixCWise](class_matrix_c_wise.xhtml "coefficient wise access to Matrix ") is deleted.
