- In the equation:
-
- XAY+XB+CY+D=0,
-
- the dimensions are: A(nxn), B(nxm), C(mxn), D(mxm), X(mxn), Y(nxm), with
- n > m. Furthermore, there is a required structure for the solutions {X,Y}.
- X must be of the structure:
-
- | xx xx .. xx 0 0 ..................................0 |
- | 0 0 ....0 .xx xx .. xx 0 .........................0 |
- | 0 0 ................0 xx xx .. xx 0 .............0 |
- | .................................................... |
- | .................................................... |
- | 0 0 ................................. 0 xx xx .. xx |
-
- and Y must be of the structure X' (note Y not = X'). Any suggestions??
