Description

ASSEMBLEPROB Assembly of system matrix and right hand side/load vector.

[ M, A, F, T_M, T_A, T_F, T_SP ] = ASSEMBLEPROB( PROB, VARARGIN ) Calls the assembly routines to compute and assemble a monolithic sparse system matrix and a right hand side/load vector as specified in the PROB struct. Accepts optional propery value pairs in VARARGIN.
