| enum LAPACKSupport::State |
Most LAPACK functions change the contents of the matrix applied to to something which is not a matrix anymore. Therefore, LAPACK matrix classes in deal.II have a state flag indicating what happened to them.
A matrix can have certain features allowing for optimization, but hard to test. These are listed here.
| const char* LAPACKSupport::state_name | ( | State | s | ) | [inline] |
Function printing the name of a State.
References eigenvalues, inverse_matrix, lu, matrix, and unusable.
| ::ExceptionBase& LAPACKSupport::ExcState | ( | State | arg1 | ) | throw (errortext << "The function cannot be called while the matrix is in state " << state_name(arg1) ) [static] |
Exception thrown when a matrix is not in a suitable state for an operation. For instance, a LAPACK routine may have left the matrix in an unusable state, then vmult does not make sense anymore.
| ::ExceptionBase& LAPACKSupport::ExcMissing | ( | char * | arg1 | ) | throw (errortext << "The function " << arg1 << " required here is missing in your LAPACK installation" ) [static] |
This exception is thrown if a certain function is not implemented in your LAPACK version.
const char LAPACKSupport::V = 'V' [static] |
Character constant.
const char LAPACKSupport::T = 'T' [static] |
Character constant.
