.. _V1.01.134: **v1.01.134** ZZZZ134 — Calculation and extraction of the discharge matrix ====================================================================== **Summary:** This test is an example of use to calculate and retrieve the discharge matrix for law RGI_BETON. A calculation is carried out with the operator STAT_NON_LINE and it is then shown how to calculate and recover the discharge matrix for a few moments of calculation given via the operator CALCUL and the keyword TYPE_MATR_TANG =' MATR_ENDO 'of COMPORTEMENT. This test validates that the value 'MATR_ENDO' of TYPE_MATR_TANG has been taken into account. This documentation is deliberately brief.
