HP 50g questions

[John Keith]

A few possible answers...

1) If what you want is to apply the function to each element in the matrix, you need to convert the matrix to a list, apply the function to the list, then convert back to a matrix. In general, unless you are doing linear algebra operations ( inverse, determinant, etc.) lists are more versatile than matrices.

2) Can't answer that one, I never use the graphing commands.

3) I don't think so.

4) You can't add user programs to built-in menus, your best bet is the Custom menu.
