Class MatFileWriter

java.lang.Object
  com.jmatio.io.MatFileWriter

public class MatFileWriter
extends Object

MAT-file writer. Usage:

 //1. First create example arrays
 double[] src = new double[] { 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 };
 MLDouble mlDouble = new MLDouble( "double_arr", src, 3 );
 MLChar mlChar = new MLChar( "char_arr", "I am dummy" );
         
 //2. write arrays to file
 ArrayList list = new ArrayList();
 list.add( mlDouble );
 list.add( mlChar );
 
 new MatFileWriter( "mat_file.mat", list );
 

this is "equal" to Matlab commands:

 >> double_arr = [ 1 2; 3 4; 5 6];
 >> char_arr = 'I am dummy';
 >>
 >> save('mat_file.mat', 'double_arr', 'char_arr');

Constructor Detail

MatFileWriter

public MatFileWriter(String fileName,
                     Collection<MLArray> data)
              throws IOException

Writes MLArrays into file given by fileName.

Parameters:

fileName - - name of ouput file

data - - Collection of MLArray elements

Throws:

IOException - if an i/o exception occurs, for instance cause by file access

MatFileWriter

public MatFileWriter(File file,
                     Collection<MLArray> data)
              throws IOException

Writes MLArrays into File.

Parameters:

file - - an output File

data - - Collection of MLArray elements

Throws:

IOException - if an i/o exception occurs, for instance cause by file access

MatFileWriter

public MatFileWriter(DataOutputStream output,
                     Collection<MLArray> data)
              throws IOException

Writes MLArrays into OuputSteram. Writes MAT-file header and compressed data (miCOMPRESSED).

Parameters:

output - - OutputStream

data - - Collection of MLArray elements

Throws:

IOException - if an i/o exception occurs, for instance cause by file access
