2013-12-03 17:05:46 +0200 | asked a question | symbolic 2x2 block matrix inversion Is it possible in SAGE to get the 2x2 block matrix inversion described in Wikipedia? I looked at this question about the determinant of block matrices, and at this question about symbolic matrices, and tried the following code on the cloud: But it doesn't seem to be able to exactly reproduce the Wikipedia formula (it returns a horrible formula full of a1, a2, etc). Any idea? |
