REDIM does not work in Home, but works in CAS. In the program can be used CAS.REDIM but it's slower than it should.

Works fine here... REDIM(M1,{2,3}), REDIM(u1,5) etc

???

It does not work:
[[1,2],[3,4]]->M1
REDIM(M1,{2,4})

The matrix is unchanged

Same here. Matrix unchanged.

To clarify, REDIM doesn't work in HOME in RPN mode. Works ok in Textbook mode.

Correction: REDIM does work in RPN mode, but you gotta use it with RPN syntax (because you're in RPN mode!). Example: 'M1' [Enter] {3,4} [Enter] REDIM [Enter]

Same here. Matrix unchanged.

Same for me, whatever the mode (RPN, textbook or algebraic).

I used the matrix template to create the matrix and then stored it in M1. Then I entered
'M1' and { 3, 4} and REDIM()--no change. Maybe something in the settings.

Anyway, does appear to be an issue here. Its on the list to resolve. Thanks.
