Hi all, Ok I figured out from the manual how to make a matrix on the 92 plus [[1,2,3][4,5,6]]->mat1 This makes the matrix with 1,2,3 as row 1 and 4,5,6 as row 2. the thing I cant get to work is how to edit them. Like for a list you do list[2] and that gives you the 2nd var in the list. But with a matrix.aint gotta clue lol. Please someone fill me in on this thnx.
