说明：  Save or display a matrix with given precision, delimiter or format for each (or every) column.
(With this program you can save (or display) your data with a different format and delimiters for every column, given as optional inputs in a user-friendly way (check the screenshot). If you don t want to deal with the format (things like 3.1f 13.4f , etc.) you can give only the precision that you want for each (or every) column (i.e. [1 4]) and the program creates the format by itself. )
