We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope. |

The randMat() command generates a random matrix: randMat(rows,columns) generates a rows by columns matrix whose entries are random integers between -9 and 9.
:RandSeed 0
:randM(3,2)
[4 -2]
[0 -7]
[8 8 ]Advanced Uses
Using the RandSeed command makes the random matrix entirely predictable: after setting the random seed to some value, the same random matrix will be returned every time (assuming the size is the same). See the RandSeed page for details of how random numbers are generated.
Error Conditions
260 - Domain error happens when the rows and columns parameters aren't positive integers..
