Change the dimension of the vector to N. The reserved memory for this vector remains unchanged if possible. If N==0, all memory is freed. Therefore, if you want to resize the vector and release the memory not needed, you have to first call init(0) and then init(N). This behaviour is analogous to that of the STL containers.

On fast==false, the vector is filled by zeros.

template<typename T >
void libMesh::EigenSparseVector< T >::localize ( std::vector< T > &  v_local,
const std::vector< numeric_index_type > &  indices 
) const
virtual

Fill in the local std::vector "v_local" with the global indices given in "indices".

Note
The indices can be different on every processor, and the same index can be localized to more than one processor. The resulting v_local can be shorter than the original, and the entries will be in the order specified by indices.

Example:

*   On 4 procs *this = {a, b, c, d, e, f, g, h, i} is a parallel vector.
*   On each proc, the indices arrays are set up as:
*   proc0, indices = {1,2,4,5}
*   proc1, indices = {2,5,6,8}
*   proc2, indices = {2,3,6,7}
*   proc3, indices = {0,1,2,3}
*
*   After calling this version of localize, the v_local vectors are:
*   proc0, v_local = {b,c,e,f}
*   proc1, v_local = {c,f,g,i}
*   proc2, v_local = {c,d,g,h}
*   proc3, v_local = {a,b,c,d}
* 

This function is useful in parallel I/O routines, when you have a parallel vector of solution values which you want to write a subset of.

Swaps the contents of this with v. There should be enough indirection in subclasses to make this an O(1) header-swap operation.
