We should implement the compressed ndarray, it is used widely in scikit-learn. The csr_matrix is included in SciPy not NumPy, but I think we should move it into NumSharp. @dotChris90 What do you think…

Docs say a scipy sparse csc matrix can be used but it can't. It works with sparse3corpus. Here is example:
```python
import gensim
from sklearn.feature_extraction.text import CountVectorizer
fro…

This is a consolidation of several matrix related tickets, e.g. #2705, #10734, #11161, #12177, #12679, #13177, #13915, #15104, ... basically, the world of matrices over finite fields. The fundamenta…

Thanks for you great (and cool) tools!
A convenience feature would be to have a function that can restore nans to an array derived from a sparse matrix using the balance weights of the cooler, sim…

### 🐛 Describe the bug
In my humble opinion, `torch.Tensor.is_sparse` should return `True` for all possible layouts of sparse matrices.
For now, I think it only does so for COO tensors. You can re…

Dear all,
I really like using ContactMap Explorer! I was wandering if there is a way to create a pandas dataframe out of a ContactFrequency calculation.
Like:
```
traj=mdt.load('trajectory.h5'…

**Motivation:** Matrix multiplications are at the heart of many machine learning algorithms, and are often very expensive operations. Therefore, highly optimized kernels exist (e.g., in BLAS). These a…

As I discovered, `scipy.sparse.linalg.eigs` is 20 times slower than octave's `eigs` for some ill-conditioned laplacian matrices as I found in https://github.com/scipy/scipy/issues/19235#issuecomment-1…

Using theano development version, commit 7943ab37580fc4f1436d93bb455ff7731be3c28d, I was able to produce this bug on Mac OS X El Capitan. Only one number in the sparse output was the correct result.
