MultiDimensional Matrices
The code below checks OK but doesn't run. Is it possible to have ndimensional tables? If so, how do you access them?

RE: MultiDimensional Matrices
The hpprime supports only up to 2D,
In a next firmware the compiler should detect the validity of an array (maximum 2D) You can work with ndimensional arrays as a list PHP Code: EXPORT mattest()

RE: MultiDimensional Matrices
You can either use lists for nonCAS programs, or you can create a CAS program that will do what you want if you specifically want to use the [ ] delimiters for your data.

RE: MultiDimensional Matrices
I'm surprised it's limited at 2D. Tensor analysis is used in a lot of engineering applications (especially mechanical engineering)....so being able to get the inverse, multiplication, etc, etc...of multidimensional arrays shouldn't be that difficult to add to the firmware...

RE: MultiDimensional Matrices
Actually, I take that back....multidimensional array operations can get very complex and are dependent on what you want to do. Classical matrix algebra doesn't go beyond 2D anyways.
