$A, B$ sparse imply $AB$ is sparse? Today I read the claim that if $A$ and $B$ are sparse matrices, then $AB$ is also sparse. I didn't believe it at first, but could not exhibit a counterexample. So is this claim in f...

Create sparse matrix - MATLAB sparse - MathWorks
example. S = sparse (i,j,v) generates a sparse matrix S from the triplets i , j, and v such that S (i (k),j (k)) = v (k). The max (i) -by- max (j) output matrix has space allotted for length (v) nonzero elements. If the inputs i, j, and v are vectors or matrices, they must have the same number of elements. Alternatively, the argument v and/or ...

Sparse matrices (cupyx.scipy.sparse) — CuPy 13.0.0 documentation
To convert SciPy sparse matrices to CuPy, pass it to the constructor of each CuPy sparse matrix class. To convert CuPy sparse matrices to SciPy, use get method of each CuPy sparse matrix class. Note that converting between CuPy and SciPy incurs data transfer between the host (CPU) device and the GPU device, which is costly in terms of performance.
