matrix with strings in Home
hi everybody,
I should use a matrix like [["First", "Second"],[1,2]] (to have a heading row). I get it in CAS, but in Home I get error. Any help, please? Salvo EDIT: about this, I should also write on a matrix (from a program) fractions, like 1/5, 2/5 ... or like strings or like symbolic fractions. Normally I get 0.2, 0.4 ... I need hints to do that. ∫aL√0mic (IT9CLU), HP Prime 50g 41CX 71b 42s 12C 15C  DM42 WP34s :: Prime Soft. Lib

A matrix is a fixed size number container. It can only support real or complex numbers. Use a list.

Use a list. hi Tim, I'd use a list, but for example with my program for Depreciation of asset I need to present data as a table (46 columns), so I thought about matrix, more immediate than a list in this case... For now, I'm presenting in another way the heading row of the matrix, then, a part of it, the matrix. Thank you for help!

It sounds like using the spreadsheet app could a solution.
