It seems like there are missing sparse matrix methods. In both 1.0.2 and 0.7 this code: using SparseArrays using LinearAlgebra A = sprand(10,10,.9) b_dense = Array(sprand(10,1,.8)) # works b_sparse = sprand(10,1,.8) # doesn't work x = A\b_dense # works x = A\b_sparse # doesn't work lu!(A) # gives …
