Detailed Description

CisMatrixReader can read a MatrixMarket formatted dense or sparse matrix from a plain text or gzipped (.gz) file or url. The url protocol has to be supported by Java such as HTTP and FTP. In order for the gzip decompression to work properly the file or url name must end in gz.

Member Function Documentation

static CisMatrix Jpetra.MatrixMarketIO.CisMatrixReader.read ( String  fileName, boolean  rowOriented, Comm  comm  ) throws java.io.IOException

inlinestatic

Reads from a MatrixMarket formatted plain text or gzipped file.

Parameters

fileName	The relative or absolute file name of the file to be read in.
rowOriented	true if the matrix should be read into row major form
comm	the comm object to be associated with the new CisMatrix

Returns

A CisMatrix that has had fillComplete called on it.

Exceptions

IOException

Any IO errors that occur while reading from the file will be thrown.

static CisMatrix Jpetra.MatrixMarketIO.CisMatrixReader.readUrl ( String  urlString, boolean  rowOriented, Comm  comm  ) throws java.io.IOException

inlinestatic

Reads a MatrixMarket formatted plain text or gzipped file from a url.

Parameters

urlString	The url in for the format protocol://location. Ex: http://test.com/matrix.gz
rowOriented	true if the matrix should be read into row major form
comm	the comm object to be associated with the new CisMatrix

Returns

A CisMatrix that has had fillComplete called on it.

Exceptions

IOException

Any IO errors that occur while reading from the url will be thrown.
