11   PetscViewerMatlabPutArray - Puts an array into the `PETSCVIEWERMATLAB` viewer.
13   Not Collective, only processor zero saves `array`
17 . m     - the first dimensions of `array`
18 . n     - the second dimensions of `array`
19 . array - the array (represented in one dimension)
20 - name  - the MATLAB name of `array`
25   Only writes `array` values on processor 0.

62   PetscViewerMatlabGetArray - Gets a variable from a `PETSCVIEWERMATLAB` viewer into an array
64   Not Collective; only processor zero reads in the array
68 . m     - the first dimensions of `array`
69 . n     - the second dimensions of `array`
70 . array - the array (represented in one dimension), must of be length `m` * `n`

155 …the fields in the MATLAB loaded da variable give the array dimensions so you can reshape the MATLAB
175               Use `PetscViewerMatlabPutArray()` to just put an array of doubles into the .mat file
