Allow creation of "incompletely" entered matrices in Spreadsheet View by assuming zeros

Alexander Perl shared this idea 4 years ago

When working with sparsely filled matrices (e.g. band matrices or upper triangular matrices), it is currently very cumbersome to enter them in the Spreadsheet View: You have to enter every single number 0 before you can convert it to a matrix. Unless you do that, the "Create Matrix" function is not even selectable, although it is absolutely clear what the user is trying to do:


My suggestion: If you enter some values in the spreadsheet window and then select a rectangular range, allow the user to create a matrix of the corresponding size by assuming 0 for every unfilled cell!
