Evaluates the given vector expression.
- Parameters
-
vector | The vector to be evaluated. |
- Returns
- The result of the evaluated vector expression.
This function forces an evaluation of the given vector expression and enables an automatic deduction of the correct result type of an operation. The following code example demonstrates its intended use for the multiplication of a dense and a sparse vector:
In this scenario, the evaluate() function assists in deducing the exact result type of the operation via the 'auto' keyword. Please note that if evaluate() is used in this way, no temporary vector is created and no copy operation is performed. Instead, the result is directly written to the target vector due to the return value optimization (RVO). However, if evaluate() is used in combination with an explicit target type, a temporary will be created and a copy operation will be performed if the used type differs from the type returned from the function:
CompressedVector<double> d( a * b );
DynamicVector<double> e( a * b );
Sometimes it might be desirable to explicitly evaluate a sub-expression within a larger expression. However, please note that evaluate() is not intended to be used for this purpose. This task is more elegantly and efficiently handled by the eval() function:
In contrast to the evaluate() function, eval() can take the complete expression into account and therefore can guarantee the most efficient way to evaluate it.
template<typename VT , bool TF>
Changing the size of the vector.
- Parameters
-
vector | The given vector to be resized. |
n | The new size of the vector. |
preserve | true if the old values of the vector should be preserved, false if not. |
- Returns
- void
- Exceptions
-
std::invalid_argument | Vector cannot be resized. |
This function provides a unified interface to resize dense and sparse vectors. In contrast to the resize()
member function, which is only available on resizable vector types, this function can be used on both resizable and non-resizable vectors. In case the given vector type VT is resizable (i.e. provides a resize()
function), the type-specific resize()
member function is called. Depending on the type VT, this may result in the allocation of new dynamic memory and the invalidation of existing views (subvectors, ...). In case VT is non-resizable (i.e. does not provide a resize()
function) and if the specified size is not identical to the current size of the vector, a std::invalid_argument exception is thrown.
