Examples of use
======================


Classic linear combination
------------------------------


.. code-block:: text

    mat_rs = COMB_MATR_ASSE (COMB_C = (_F (MATR_ASSE = mat_1,
COEF_R = 1. ),
_F (MATR_ASSE = mat_2,
COEF_C = ('RI', 0.,1.,),)
,),)

The product concept mat_rs is of the type Matr_asse_*_c (complex):


.. code-block:: text
 mat_rs = mat_1 + i mat_2


Copy of a concept of type Matr_asse_*_r
------------------------------------------


.. code-block:: text

    mat_save = COMB_MATR_ASSE (COMB_R = _F (MATR_ASSE = mat_1,
COEF_R = 1.))


Difference between COMB_C and COMB_R:
-----------------------------------


.. code-block:: text

    Mat_r = COMB_MATR_ASSE (COMB_R = _F (MATR_ASSE = mat_1,
COEF_R = 1.))


    # Mat_r has real coefficients Mat_r = mat_1


    Mat_c = COMB_MATR_ASSE (COMB_C = _F (MATR_ASSE = mat_1,
COEF_R = 1.))


    # Mat_c has complex coefficients, but the imaginary part is zero Mat_c = mat_1 + i. [:ref:`0 <0>`].


Extracting the real part of a matr_asse_*_c matrix
