Description :

Performs various operations which do not fit elsewhere.

Command list :

gf_util('save matrix', string FMT, string FILENAME, mat A)

Exports a sparse matrix into the file named FILENAME, using Harwell-Boeing (FMT=’hb’) or Matrix-Market (FMT=’mm’) formatting.

A = gf_util('load matrix', string FMT, string FILENAME)

Imports a sparse matrix from a file.

tl = gf_util('trace level' [, int level])

Set the verbosity of some GetFEM routines.

Typically the messages printed by the model bricks, 0 means no trace message (default is 3). if no level is given, the current trace level is returned.

tl = gf_util('warning level', int level)

Filter the less important warnings displayed by getfem.

0 means no warnings, default level is 3. if no level is given, the current warning level is returned.

tl = gf_util('set num threads', int nb_threads)

Sets the number of threads for the multithreaded GetFEM version. It is available only when GetFEM is compiled with openmp support.
