QrStructuralCounts_FSCC (ejml-fsparse 0.39 API)

java.lang.Object
- org.ejml.sparse.csc.decomposition.qr.QrStructuralCounts_FSCC

```
public class QrStructuralCounts_FSCC
extends java.lang.Object
```
Determines the structure of the QR decomposition. Both R and V (householder vectors) component.
Fictional Rows: When there are no non-zero values in a row a fictional row is added to the end. The fictional row will have an element in it that is not zero. It will then be permuted in. The QR decomposition algorithm requires that all rows have a structurally non-zero element in them.

NOTE: This class contains the all of or part of cs_sqrt() and cs_vcounts() in csparse

```
public boolean process(org.ejml.data.FMatrixSparseCSC A)
```
    Examins the structure of A for QR decomposition
    
    Parameters:
    
    A - matrix which is to be decomposed
    
    Returns:
    
    true if the solution is valid or false if the decomposition can't be performed (i.e. requires column pivots)
