Matrix Operations

These APDL Math commands can be used to create, manipulate, and solve matrices.


See the APDL Math Overview for a more pythonic way of interacting with APDLMath.

Mapdl.axpy([vr, vi, m1, wr, wi, m2])

Performs the matrix operation M2= v*M1 + w*M2.

Mapdl.comp([matrix, algorithm, threshold])

Compresses the columns of a matrix using a specified algorithm.

Mapdl.dmat([matrix, type_, method, val1, ...])

Creates a dense matrix.[vector1, vector2, par_real, par_imag])

Computes the dot (or inner) product of two vectors.
