VecView

Views a vector object.

int VecView(Vec vec,PetscViewer viewer)

Collective on Vec

	v	- the vector
	viewer	- an optional visualization context

The available visualization contexts include

	PETSC_VIEWER_STDOUT_SELF	- standard output (default)
	PETSC_VIEWER_STDOUT_WORLD	- synchronized standard output where only the first processor opens the file. All other processors send their data to the first processor to print.

You can change the format the vector is printed using the option PetscViewerSetFormat().

The user can open alternative visualization contexts with

	PetscViewerASCIIOpen()	- Outputs vector to a specified file
	PetscViewerBinaryOpen()	- Outputs vector in binary to a specified file; corresponding input uses VecLoad()
	PetscViewerDrawOpen()	- Outputs vector to an X window display
	PetscViewerSocketOpen()	- Outputs vector to Socket viewer

The user can call PetscViewerSetFormat() to specify the output format of ASCII printed objects (when using PETSC_VIEWER_STDOUT_SELF, PETSC_VIEWER_STDOUT_WORLD and PetscViewerASCIIOpen). Available formats include

	PETSC_VIEWER_ASCII_DEFAULT	- default, prints vector contents
	PETSC_VIEWER_ASCII_MATLAB	- prints vector contents in Matlab format
	PETSC_VIEWER_ASCII_INDEX	- prints vector contents, including indices of vector elements
	PETSC_VIEWER_ASCII_COMMON	- prints vector contents, using a format common among all vector types
