CSVREAD  CSVREAD Read Comma Separated Value (CSV) File


Usage
 
 The csvread function reads a text file containing comma
 separated values (CSV), and returns the resulting numeric
 matrix (2D).  The function supports multiple syntaxes.  The
 first syntax for csvread is 
 
    x = csvread('filename')
 
 which attempts to read the entire CSV file into array x.
 The file can contain only numeric values.  Each entry in the
 file should be separated from other entries by a comma.  However,
 FreeMat will attempt to make sense of the entries if the comma
 is missing (e.g., a space separated file will also parse correctly).
 For complex values, you must be careful with the spaces).  The second
 form of csvread allows you to specify the first row and column 
 (zero-based index)
 
   x = csvread('filename',firstrow,firstcol)
 
 The last form allows you to specify the range to read also.  This form
 is
 
   x = csvread('filename',firstrow,firstcol,readrange)
 
 where readrange is either a 4-vector of the form [R1,C1,R2,C2],
 where R1,C1 is the first row and column to use, and R2,C2 is the
 last row and column to use.  You can also specify the readrange as
 a spreadsheet range B12..C34, in which case the index for the
 range is 1-based (as in a typical spreadsheet), so that A1 is the
 first cell in the upper left corner. Note also that csvread is
 somewhat limited.  The number of columns in the file cannot exceed
 65535.  If it does, bad things will happen.
