#8277: Using matrix() to convert between sparse and dense.
------------------------------+---------------------------------------------
Reporter: hivert | Owner: hivert
Type: defect | Status: new
Priority: major | Milestone: sage-4.3.3
Component: algebra | Keywords: sparse matrix conversion

------------------------------+---------------------------------------------
A call to {{{matrix}}} does not change the sparsity:
{{{
sage: mat = matrix(ZZ, [[1,1],[1,1]], sparse=False)
sage: type(mat)
<type 'sage.matrix.matrix_integer_dense.Matrix_integer_dense'>
sage: mat2 = matrix(ZZ, mat, sparse=True)
sage: type(mat2)
<type 'sage.matrix.matrix_integer_dense.Matrix_integer_dense'>
}}}
