One correction... the routine for comparing matrices is
linalg[equal]
I had said the routine was linalg[equality], which is incorrect. You
can use linalg/equal for vectors and matrices (which are one and
two-dimensional arrays with indices starting at one). The only way I
know of to compare more general arrays like:
array(-1..2,[1,2,3,4]):
is the painful way... by comparing the both the range indices and all
the elements of the array. There are lots of ways you can do this,
but they boil down to writing about a half dozen lines of code.
