"CMAT is an HP48 program for performing operations on columns of a
matrix. CMAT iterates over each row of the matrix, treating the n
columns of the matrix as if they were variables named C1, C2, ...
Cn, or, optionally, as if they were named with user-specified
names."

Does a matrix allow (x,y) points to be stored in one position?

What do you use as a data collector these days? I used an HP48GX like most everyone in the early 2000s. I still have my gun and 48 with cards.
