I am solving a linear system where the LHS is a diagonal matrix and the RHS is the transpose of a sparse matrix. The resulting sparse matrix has all its zeros filled in. I show an example where I firs…

Some functions have sparse Jacobian or sparse Hessian and it can be usefull to obtain them as sparse matrices rather than accessing to the values through vector-jacobian or vector-hessian products fu…

### Is your feature request related to a problem? Please describe.
As far as I can tell, there is no good way to estimate the condition number of sparse matrices in scipy.

It's a minor issue, but I accidentally evaluated a large sparse matrix (~500M rows) in REPL and it caused a ~5-second freeze. Not sure what's happening under the hood but I assume it tries to output a…
