ansys.mapdl.core.math.MapdlMath

class ansys.mapdl.core.math.MapdlMath(mapdl)

Abstract mapdl math class. Created from a Mapdl instance.

Examples

Create an instance.

>>> from ansys.mapdl.core import launch_mapdl
>>> mapdl = launch_mapdl()
>>> mm = mapdl.math

Vector addition

>>> v1 = mm.ones(10)
>>> v2 = mm.ones(10)
>>> v3 = v1 + v2

Matrix multiplcation (not yet available)

>>> v1 = mm.ones(10)
>>> m1 = mm.rand(10, 10)
>>> v2 = m1*v1
