hypermatrices

Description

Hypermatrix type allows to manipulate multidimensional arrays.

They can be defined by extension of 2D matrices as follows a=[1 2;3 4];a(:,:,2)=rand(2,2) or directly using matrix function.

Entries can be booleans, encoded integers of any inttype, real or complex numbers, polynomials, rationals, strings, booleans.

The number of dimension of hypermatrices with right-most sizes equal to 1 are automatically reduced. An hypermatrix with only two dimensions is automatically changed to a regular matrix (type 1).

Examples

a(1,1,1,1:2)=[1 2]
a=[1 2;3 4];a(:,:,2)=rand(2,2)
a(1,1,:)

size(a)

a(:,:,1) //dimensionality reduction
type(a(:,:,1))

[a a]
