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

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

class | blaze::UniUpperValue< MT > |
| Representation of a value within a sparse upper unitriangular matrix.The UniUpperValue class represents a single value within a sparse upper unitriangular matrix. It guarantees that the uniupper 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 uniupper matrix is in default state.
- Parameters
-
m | The uniupper matrix to be tested for its default state. |
- Returns
- true in case the given matrix is component-wise zero, false otherwise.
This function checks whether the upper unitriangular matrix is in default state. The following example demonstrates the use of the isDefault function:
UniUpperMatrix< DynamicMatrix<int,rowMajor> > 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 uniupper value is in default state.
- Parameters
-
value | The given uniupper value. |
- Returns
- true in case the uniupper value is in default state, false otherwise.
This function checks whether the uniupper 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 uniupper matrix are intact.
- Parameters
-
m | The uniupper 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 uniupper 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:
UniUpperMatrix< DynamicMatrix<int> > A;
template<bool RF, typename MT >
Returns whether the uniupper value is 1.
- Parameters
-
value | The given uniupper value. |
- Returns
- true in case the uniupper value is 1, false otherwise.
This function checks whether the uniupper 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 uniupper value represents a real number.
- Parameters
-
value | The given uniupper value. |
- Returns
- true in case the uniupper value represents a real number, false otherwise.
This function checks whether the uniupper 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 uniupper value is 0.
- Parameters
-
value | The given uniupper value. |
- Returns
- true in case the uniupper value is 0, false otherwise.
This function checks whether the uniupper 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 uniupper matrix.
- Parameters
-
m | The uniupper 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 uniupper 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.
