VecSet

Sets all components of a vector to a single scalar value.

Synopsis

#include "petscvec.h" 
int VecSet(const PetscScalar *alpha,Vec x)

Collective on Vec

Input Parameters

	alpha	- the scalar
	x	- the vector

Output Parameter

x -the vector

Note

For a vector of dimension n, VecSet() computes

    x[i] = alpha, for i=1,...,n,

so that all vector entries then equal the identical scalar value, alpha. Use the more general routine VecSetValues() to set different vector entries.
