The primary source code repository for Macaulay2, a system for computing in commutative algebra, algebraic geometry and related fields.
I'm not sure if this is really a bug, but this is something that's been bothering me for a while. currently, some links are broken in the help for me:...
I got a strange error running the script that generates cached examples for the Debian package. I was able to isolate the problem down to the following steps:. * Load...
Macaulay2 seems to give strange betti tables for modules over rings with variables of degree 0. ``` i1 : S = ZZ/101[x,y,Degrees => {{0},{1}}] o1 = S o1 : PolynomialRing...
It's annoying that this doesn't work: ```m2 i1 : methods matrix o1 = {0 => (matrix, List) } {1 => (matrix, Matrix) } {2 => (matrix, MutableMatrix) } {3 =>...
Promotion of mutable matrices doesn't work: (so mutablemat.m2:83-89 and enginering.m2:135-139 don't actually work) ``` i1 : m=mutableMatrix {{1}} o1 = | 1 | o1 : MutableMatrix i2 : promote(m,QQ) stdio:3:1:(3):...
The monomial cones in the decomposition come out not disjoint: ``` i1 : QQ[x,y,z]; standardPairs monomialIdeal(x*y^3*z, x*y^2*z^2) 2 o2 = {{1, {y, z}}, {1, {x, z}}, {y, {x, z}}, {1,...
In `M2/Macaulay2/packages/Macaulay2Doc/overview3.m2` we insert an image into the documentation using the expression ``` replace("PKG","Style",currentLayout#"package") | "eisenbud.jpg" ``` . This won't work when installing into the user application directory and running...
The documentation for 'depth(Ideal,Ring)' should also cover the case 'depth(Ideal,Module)'.
Sorry if this isn't the right place (ie, do Documentation Issues go here?), but the function flattenRing asserts: > write a ring as a (quotient) of a polynomial ring over...
