Mapdl.export(matrix='', format_='', fname='', val1='', val2='', val3='', **kwargs)[source]#

Exports a matrix to a file in the specified format.



Name of the matrix to export (must be a matrix previously created with *DMAT or *SMAT, or a vector previously created with *VEC).


Format of the output file:

Export the matrix in the Matrix Market Format. - Export the matrix in the SUB file format.

Export the matrix in the Harwell-Boeing file format. - Export the matrix in a native format, to be re-imported using the *DMAT or *SMAT command.

Export the matrix to an existing EMAT file. - Export the matrix to an APDL array parameter.

Export the matrix profile to a Postscript file. - Export the matrix in the DMIG file format.


Name of the file, or name of the array parameter if Format = APDL.

val1, val2, val3

Additional input. The meaning of Val1 through Val3 will vary depending on the specified Format. See table below for details.


Only sparse matrices can be exported to Postscript files. This option plots the matrix profile as a series of dots.

If you want to create a .SUB file from several matrices, you need to set Val3 = WAIT for all matrices but the last, and Val3 = DONE for the last one. The export will be effective at the last *EXPORT command.

To create a .SUB file or .DMIG file from scratch, you must supply the row information array. (Specify this array in the Val2 field for .SUB or in the Val1 field for .DMIG.) This must be an m x 2 array, where m is the size of the matrix. The first column is the node number and the second column is the DOF number corresponding to each row of the matrix.

The *EXPORT command is not applicable to sparse matrices initialized from .FULL files by means of the NOD2BCS option on the *SMAT command (i.e., *SMAT,,,IMPORT,FULL,,NOD2BCS).
