| Assume that Li are known,
then PM is known. |
|||||||||||
| Use the singular
value decomposition |
|||||||||||
| PM=US VT |
|||||||||||
| In the noise-free
case |
|||||||||||
| S=diag(s1,s2,s3,s4,0, … ,0) |
|||||||||||
| and a
reconstruction can be obtained by setting: |
|||||||||||
| P=the first four columns of US. |
|||||||||||
| M=the first four rows of V. |
