Computing the syndrome of a vector is useful for many things (eg: decoding) in coding theory, but linear code does not have any syndrome method.
Besides, actual parity-check matrix computation crea…

I am struggling to run some QC routines like those found in `compute_for_mcview`.
In particular:
```
- compute_inner_fold_factors
- compute_deviant_fold_factors
```
I've noticed tha…

Something is wrong with the multi-modular matrix multiplication code for matrices over ZZ. At random, and infrequently, it gives incorrect results. For example, the following code chooses random 3…

`sage.coding.linear_code` has a number of global functions and class methods which are badly named, badly documented, badly placed or badly conceived. This ticket takes some steps towards cleaning u…

I randomly get issues with any example code that uses zones: most of the time, sketches work fine after uploading (every now and then even a fresh upload fails, though, and keeps failing until I uploa…

Sorry for asking you quite often, but let me ask about time-varying regression with SSMregression terms included.
I'm using a model like below:

For some double dense matrices that are not positive definite, Sage incorrectly claims that they are:
```
sage: A = matrix(CDF, [[1+I]])
sage: A.is_positive_definite() # should be Fals…
