rowcol-0.1.0 has been yanked.
rowcol crate provides fixed-size Vector and Matrix.
Their length or number of rows/columns are provided as type parameter
using type-level numerics provided by typenum crate.
This let vectors and matrices be internally represented as fixed-length arrays,
therefore they are allocated on the stack, and becomes Copy if their content
is Copy. Also, errors like computing the determinant of a non-square matrix
can be detected at compile-time, instead of runtime panic.
