If all else fails you can dump the data to a text file and use one of
the converters in the bin/convert dir.
TextToColorMap TextToHexVolField TextToStructHexVolField
TextToColumnMatrix TextToPointCloudField TextToStructQuadSurfField
TextToCurveField TextToPointCloudString TextToTetVolField
TextToDenseMatrix TextToQuadSurfField TextToTriSurfField
TextToHexTricubicHmt TextToStructCurveField

Use the module "ImportFieldsFromMatlab" and use the field.mat file.

Now I am not sure what kind of mesh you want to create:
