| ## 4.21 smatrix An experimental type: Objects of type smatrix are (sparse) matrices with polynomial entries. Like polynomials they can only be defined or accessed with respect to a basering. Objects of type `smatrix` can be converted to and from `matrix` and `module`. Operations are `+`, `-`, `*`, `==`, `<>`. Functions are `chinrem`, `farey`, `ncols`, `nrows`, `std`, `transpose`, `tensor`. Additional `flatten(m)` and `system("unflatten",m,col)`. Resizing can be done via `smatrix(m,r,c)` where m is of type `module` or `smatrix`. Access to single entries: `m[i,j]` See chinrem; farey; flatten; matrix; module; ncols; nrows; ring; std; tensor; transpose.
