Importing and exporting matrix definitions from and to CSV

You can export the definition of a matrix to a comma-separated values (CSV) file. You can edit the exported definition and then import it again. To use this feature, you must first add all matrix columns in the correct order. When exporting to CSV, the matrix definition is preserved. You can add rows to extend the matrix definition. When importing from CSV, the matrix that you import must match the matrix definition it is imported into.
