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. |
Divides two values, doing so element-by-element for two matrices.
value ./ value
Menu Location
- Press 2nd MATH to enter the MATH menu.
- Press 4 to enter the Matrix submenu.
- Press K to enter the Element ops submenu.
- Press 4 to select ./.
…frankly, just typing it is way easier.
This command works on all calculators.
1 byte
The ./ operator works just like / in most cases. The only exception is with matrices. The / command can't do anything with then (except for dividing a matrix by a value), but ./ will just apply the operation element-by-element. Obviously, when this is done for two matrices, their dimensions have to match up.
:[a,b;c,d] ./ [e,f;g,h]
[a/e b/f]
[c/g d/h]When dividing a constant number by a matrix with ./, you may need to space it out so that there's no confusion between ./ and a decimal point.
:1./[a,b;c,d]
