## Detailed Description

The RefDiagSCMatrix class is a smart pointer to an DiagSCMatrix specialization.

## Constructor & Destructor Documentation

sc::RefDiagSCMatrix::RefDiagSCMatrix | ( |  | ) |

Initializes the matrix pointer to 0.

The reference must be initialized before it is used.

sc::RefDiagSCMatrix::RefDiagSCMatrix | ( | const RefSCDimension & | ,
|  | const Ref< SCMatrixKit > & |  |
| ) |  |  |

Create a diagonal matrix with dimension d by d.

The data values are undefined.

## Member Function Documentation

RefDiagSCMatrix sc::RefDiagSCMatrix::clone | ( |  | ) | const

These call the SCMatrix members of the same name after checking for references to 0.

int sc::RefDiagSCMatrix::nblock | ( |  | ) | const

If this matrix is blocked return the number of blocks.

Otherwise return 1.

RefDiagSCMatrix sc::RefDiagSCMatrix::block | ( | int | i | ) | const

If this matrix is blocked return block i.

Otherwise return this as block 0.
