* Finally added `array-axis-expand' as a dual for `array-axis-reduce' in order to implement `vandermonde-matrix' elegantly * Better, shorter matrix multiply; reworked all matrix arithmetic * Split "matrix-operations.rkt" into at least 5 parts: * "matrix-operations.rkt" * "matrix-basic.rkt" * "matrix-comprehension.rkt" * "matrix-sequences.rkt" * "matrix-column.rkt" Added "matrix-constructors.rkt" Added `matrix', `row-matrix', and `col-matrix' macros A lot of other little changes Currently, `in-row' and `in-column' are broken. I intend to implement them in a way that makes them work in untyped and Typed Racket.
