class | blaze::UniLowerElement< MT > |
| Representation of an element within a sparse lower unitriangular matrix.The UniLowerElement class represents an element (i.e. value/index pair) within a sparse lower unitriangular matrix. It guarantees that the unilower matrix invariant is not violated, i.e. that elements in the upper part of the matrix remain 0 and the diagonal elements remain 1. The following example illustrates this by means of a sparse lower unitriangular matrix: More...

class | blaze::UniLowerProxy< MT > |
| Access proxy for lower unitriangular matrices.The UniLowerProxy provides controlled access to the elements of a non-const lower unitriangular matrix. It guarantees that the unilower matrix invariant is not violated, i.e. that elements in the upper part of the matrix remain 0 and the diagonal elements remain 1. The following example illustrates this by means of a dense lower unitriangular matrix: More...

class | blaze::UniLowerValue< MT > |
| Representation of a value within a sparse lower unitriangular matrix.The UniLowerValue class represents a single value within a sparse lower unitriangular matrix. It guarantees that the unilower matrix invariant is not violated, i.e. that elements in the upper part of the matrix remain 0 and the diagonal elements remain 1.

template<bool RF, typename MT , bool SO, bool DF>
Returns whether the given unilower matrix is in default state.
- Parameters
-
m | The unilower matrix to be tested for its default state. |
- Returns
- true in case the given matrix is in default state, false otherwise.
This function checks whether the lower unitriangular matrix is in default state. The following example demonstrates the use of the isDefault function:
UniLowerMatrix< DynamicMatrix<int> > A;
Optionally, it is possible to switch between strict semantics (blaze::strict) and relaxed semantics (blaze::relaxed):
if( isDefault<relaxed>( A ) ) { ... }
template<bool RF, typename MT >
Returns whether the unilower value is in default state.
- Parameters
-
value | The given unilower value. |
- Returns
- true in case the unilower value is in default state, false otherwise.
This function checks whether the unilower value is in default state. In case it is in default state, the function returns true, otherwise it returns false.
template<bool RF, typename MT >
Returns whether the represented element is in default state.
- Parameters
-
proxy | The given access proxy |
- Returns
- true in case the represented element is in default state, false otherwise.
This function checks whether the element represented by the access proxy is in default state. In case it is in default state, the function returns true, otherwise it returns false.
template<typename MT , bool SO, bool DF>
Returns whether the invariants of the given unilower matrix are intact.
- Parameters
-
m | The unilower matrix to be tested. |
- Returns
- true in case the given matrix's invariants are intact, false otherwise.
This function checks whether the invariants of the unilower matrix are intact, i.e. if its state is valid. In case the invariants are intact, the function returns true, else it will return false. The following example demonstrates the use of the isIntact() function:
UniLowerMatrix< DynamicMatrix<int> > A;
template<bool RF, typename MT >
Returns whether the unilower value is 1.
- Parameters
-
value | The given unilower value. |
- Returns
- true in case the unilower value is 1, false otherwise.
This function checks whether the unilower value represents the numeric value 1. In case it is 1, the function returns true, otherwise it returns false.
template<bool RF, typename MT >
Returns whether the represented element is 1.
- Parameters
-
proxy | The given access proxy. |
- Returns
- true in case the represented element is 1, false otherwise.
This function checks whether the element represented by the access proxy represents the numeric value 1. In case it is 1, the function returns true, otherwise it returns false.
template<bool RF, typename MT >
Returns whether the unilower value represents a real number.
- Parameters
-
value | The given unilower value. |
- Returns
- true in case the unilower value represents a real number, false otherwise.
This function checks whether the unilower value represents the a real number. In case the value is of built-in type, the function returns true. In case the element is of complex type, the function returns true if the imaginary part is equal to 0. Otherwise it returns false.
template<bool RF, typename MT >
Returns whether the matrix element represents a real number.
- Parameters
-
proxy | The given access proxy. |
- Returns
- true in case the matrix element represents a real number, false otherwise.
This function checks whether the element represented by the access proxy represents the a real number. In case the element is of built-in type, the function returns true. In case the element is of complex type, the function returns true if the imaginary part is equal to 0. Otherwise it returns false.
template<bool RF, typename MT >
Returns whether the unilower value is 0.
- Parameters
-
value | The given unilower value. |
- Returns
- true in case the unilower value is 0, false otherwise.
This function checks whether the unilower value represents the numeric value 0. In case it is 0, the function returns true, otherwise it returns false.
template<bool RF, typename MT >
Returns whether the represented element is 0.
- Parameters
-
proxy | The given access proxy. |
- Returns
- true in case the represented element is 0, false otherwise.
This function checks whether the element represented by the access proxy represents the numeric value 0. In case it is 0, the function returns true, otherwise it returns false.
template<typename MT , bool SO, bool DF>
Resetting the specified row/column of the given unilower matrix.
- Parameters
-
m | The unilower matrix to be resetted. |
i | The index of the row/column to be resetted. |
- Returns
- void
This function resets the values in the specified row/column of the given unilower matrix to their default value. In case the given matrix is a rowMajor matrix the function resets the values in row i, if it is a columnMajor matrix the function resets the values in column i. Note that the capacity of the row/column remains unchanged.
