1) Given that we can attach null spaces to KSP, Do you believe there are good use cases for attaching them to Mat?
2) Given that currently the A and B operators of KSP actually live inside the PC, perhaps the KSP null space should also live inside the PC, ant PC should be in charge of removing the null space. What do you think about this? -- Lisandro Dalc?n --------------- Centro Internacional de M?todos Computacionales en Ingenier?a (CIMEC) Instituto de Desarrollo Tecnol?gico para la Industria Qu?mica (INTEC) Consejo Nacional de Investigaciones Cient?ficas y T?cnicas (CONICET) PTLC - G?emes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594
