Macaulay2
The primary source code repository for Macaulay2, a system for computing in commutative algebra, algebraic geometry and related fields.
cdb is a faster database suite than gdbm, which we use, so replace it. See the benchmarks at https://gist.github.com/epitron/1625d93d0b82c32e7395
```m2 needsPackage "NormalToricVarieties" X = toricProjectiveSpace 1 ** toricProjectiveSpace 2 HH^1(X, OO_X(-2,2)) -- QQ^6 Ext^1(OO_X, OO_X(-2,2)) -- 0 ``` The two vector spaces should be equal (Hartshorne III 6.3), and...
There's an unused m2 type `FilePosition` which I think would be useful for debugging purposes. It seems similar to the d type Position except for the fact that it's missing...
The function "frames" is exported and documented, but the similar function, "frame", is not. (A local frame is a sequence of values for the local variables in a function closure....
The following code produces an error because the ambient free module of M has a Schreyer order, whereas the ambient free module of 0*M does not (the free modules mentioned...
See for instance: [linSpace](http://www2.macaulay2.com/Macaulay2/doc/Macaulay2/share/doc/Macaulay2/Polyhedra/html/_lin__Space.html).  Perhaps this should raise an error.
Here is a suggestion: instead of organizing the `packages` directory as: ``` Macaulay2/packages/ ... ├── Matroids.m2 ├── Matroids │ └── SmallMatroids.txt ... ``` let's allow having packages contained in another...
I believe this should be an error: ```m2 i1 : R = kk[x]; i2 : M = module ideal x^2; i3 : N = comodule ideal x^2; i4 : M...
Using the [Macaulay2Web Server](https://www.unimelb-macaulay2.cloud.edu.au/#home), the output of computations is always generate to TeX. This is definitely not a good behaviour for users of packages like MultiprojectiveVarieties where the support to...
From a [continuous integration test of the i386 Macaulay2 1.19 package in Debian unstable](https://ci.debian.net/data/autopkgtest/testing/i386/m/macaulay2/16789084/log.gz): ```m2 -- capturing check(4, "K3Surfaces") -- 1.92545 seconds elapsed -- capturing check(5, "K3Surfaces") -- 9.40628 seconds...
