csvwrite

Write a comma-separated value file

Syntax

• csvwrite('filename',M)
  csvwrite('filename',M,row,col)
  

Description

csvwrite('filename',M) writes matrix M into filename as comma-separated values.

csvwrite('filename',M,row,col) writes matrix M into filename starting at the specified row and column offset. The row and column arguments are zero-based, so that row=0 and C=0 specifies the first value in the file.

Examples

The following example creates a comma-separated value file from the matrix, m.

• m = [3 6 9 12 15; 5 10 15 20 25; 7 14 21 28 35; 11 22 33 44 55];
  
  csvwrite('csvlist.dat',m)
  type csvlist.dat
  
  3,6,9,12,15
  5,10,15,20,25
  7,14,21,28,35
  11,22,33,44,55
  

The next example writes the matrix to the file, starting at a column offset of 2.

• csvwrite('csvlist.dat',m,0,2)
  type csvlist.dat
  
  ,,3,6,9,12,15
  ,,5,10,15,20,25
  ,,7,14,21,28,35
  ,,11,22,33,44,55
