CSVWRITE CSVWRITE Write Comma Separated Value (CSV) File

Usage

The csvwrite function writes a given matrix to a text
file using comma separated value (CSV) notation.  Note that
you can create CSV files with arbitrary sized matrices, but
that csvread has limits on line length.  If you need to
reliably read and write large matrices, use rawwrite and
rawread respectively.  The syntax for csvwrite is 

   csvwrite('filename',x)

where x is a numeric array.  The contents of x are written
to filename as comma-separated values.  You can also specify
a row and column offset to csvwrite to force csvwrite to
write the matrix x starting at the specified location in the 
file.  This syntax of the function is

   csvwrite('filename',x,startrow,startcol)

where startrow and startcol are the offsets in zero-based
indexing.
