*Improve QR factorization by replacing CXSPARSE code with SPQR code, and make the linear solve return 2-norm solutions for ill-conditioned matrices based on this new code
*Improve QR factorization by replacing CXSPARSE code with SPQR code, and make the linear solve return 2-norm solutions for ill-conditioned matrices based on this new code


*Implement fourth argument to the sprand and sprandn, and addition arguments to sprandsym that the leading brand implements.
*Improve Matlab compatibility for {{manual|sprandsym}}.


*Sparse logical indexing in idx_vector class so that something like 'a=sprandn(1e6,1e6,1e-6); a(a<1) = 0' won't cause a memory overflow.
*Sparse logical indexing in idx_vector class so that something like <code>a = sprandn (1e6, 1e6, 1e-6); a(a<1) = 0;</code> won't cause a memory overflow.
