TI-Nspire: Transmit Parameters to Func/Prog

The Background
I'm trying to program a function for TI-Nspire CAS Handheld. The function should determine the properties of one or more matrices like orthonormality.

The Problem
I don't know how to transmit the matrices as parameters to the function. Does someone know if it's possible, or know any syntax example?

Solution

  • It depends:

    If you are trying to do in TI-Basic you simply pass the matrix as a parameter (if you don't want to do that, store it in a global variable and access it directly).

    If you are doing it from a Lua program, it's a little more complicated, because TI-Basic doesn't support tables inside matrices, while Lua does. For example, you could try math.eval("MyCalculatorFunction({{1,2},{3,4}})") which would call the TI-Basicfunction "MyCalculatorFunction" with the 2x2 matrix: [1 2] [3 4]. But you CANNOT do math.eval("MyCalculatorFunction({{{1}}})"), because TI-Basic doesn't support 3D Matrices.

    Also, from a Lua script you can only call TI-Basic FUNCTIONS (NOT PROGRAMS). That means, you can't do TI-Basic graphics or pop-up windows from a Lua script.
