more-than-2 dimensions matrix

Hi,

Is it possible *somehow* in Mathcad to have more-than-2 dimension matrix ? I don't want to represent them (that would be really awkard), just to define and read the elements, do some math ... the usual.

The only thing I saw that came close was to use nested matrix, but that gets a bit messy in terms of reading. X[a,b,c looks a lot better than ((X[a)[b)[c ...

Thanks

We have complained about this for many years too. The very obvious indexing schemes such as you show only work on the rhs of an assignment operator, not on the lhs. It makes for some additional pain when using nested arrays!

We have been asking for multidimensional arrays for at least the last 15 years. Mathsoft never gave any indication that they listened to the numerous requests for this feature, and when PTC purchased Mathsoft they apparently purchased the deafness along with the product. So the only solution is a hack job using nested arrays.

Hi Adrien,

unfornately no! It is not possible. I hope that MC prime will some day introduce 3D matricees. Until then we'll have to cope with PTC's "messy" implementation of matrix definitions.

Thanks a lot. Nested matrix it will be then. *sigh*

I guess the next question is : What am I doing wrong in declaring my nested matrix ? A general declaration with all indexes varying doesn't seem to work. I assume a loop would do it, but that's a bit of a pain.
