- I am trying to solve the matrix equation:
-
- XAY + XB + CY + D = 0,
-
- where A is (nxn), B (nxm), C (mxn) and D (mxm) with n > m. Furthermore,
- the unknown matrices {X,Y} must be of a particular structure, namely X must
- have the structure:
-
- | xx xx .. xx 0 ...................................0 |
- | 0 0 .. 0 xx xx .. xx 0 .......................0 |
- | 0 0 ...............0 xx xx .. xx 0 .............|
- | .................................................. |
- | 0 0 ..............................0 xx xx .. xx |
-
- and Y must have the structure Y=X' (note Y not= X). Any ideas, comments etc?
