# matrix

Takes a list of (integer, boolean or enumerated) domains for its indices and a domain for the entries.

Defined by
` matrix indexed by [COMMA SEPARATED DOMAIN LIST] of [DOMAIN]`

as demonstrated here.

or by explicity defining values in square brackets like
` letting M be [0,1]`

The domain used to index the elements may be specifed too, such that.
`[0,1]`

is the same as `[0,1; int(1..2)]`

but different from `[0,1; int(0..1)]`

They are not ordered, but can be compared using equality operators. Two matrices are only equal if their indices are the same.
