Detailed Description
The RefSCMatrix class is a smart pointer to an SCMatrix specialization.
Constructor & Destructor Documentation
◆ RefSCMatrix() [1/2]
| sc::RefSCMatrix::RefSCMatrix | ( | ) |
Initializes the matrix pointer to 0.
The reference must be initialized before it is used.
◆ RefSCMatrix() [2/2]
| sc::RefSCMatrix::RefSCMatrix | ( | const RefSCDimension & | d1, |
| const RefSCDimension & | d2, | ||
| const Ref< SCMatrixKit > & | |||
| ) |
Create a vector with dimension d1 by d2.
The data values are undefined.
Member Function Documentation
◆ block()
| RefSCMatrix sc::RefSCMatrix::block | ( | int | i | ) | const |
If this matrix is blocked return block i.
Otherwise return this as block 0.
◆ nblock()
| int sc::RefSCMatrix::nblock | ( | ) | const |
If this matrix is blocked return the number of blocks.
Otherwise return 1.
◆ solve_lin()
| double sc::RefSCMatrix::solve_lin | ( | const RefSCVector & | v | ) | const |
Solves this x = v.
Overwrites v with x.
◆ svd()
| void sc::RefSCMatrix::svd | ( | const RefSCMatrix & | U, |
| const RefDiagSCMatrix & | sigma, | ||
| const RefSCMatrix & | V | ||
| ) |
Compute the singular value decomposition, this = U sigma V.t().
The dimension of sigma is the smallest dimension of this. U, V, and sigma must already have the correct dimensions and are overwritten.
