Perhaps the best is what the second poster suggested, simply use the built-in Matrix Writer to construct your matrix, then use the wealth of 48 matrix commands to do whatever you wish. If you prefer command line entry, another way is to use the ROW-> command, which transforms row vectors into a matrix. There are also a number of element commands which I won't detail here.
Since you're a beginning programmer, there are a number of good books available on programming the 48, which also work on the 49/49+. Probably the best one to start with is "An Easy Course in Using & Programming the 48" by GrapeVine Publications: http://www.read-gpi.com/ If you find you like programming, get a copy of the 48 Series Advanced Users Reference Manual, or AUR. It provides a detailed description of every command available in the 48 ROM.
As I play with my old 48, I find it very slow compared with the 49 series. If possible, experiment with a 49/49+, you may find you like the increased speed as well as a true Computer Algebra System included. If your calculator is a GX in good shape, you will probably be able to sell it on eBay for much more than you'll pay for two 49s! Best of luck.
