 -- Function File: x = csvread (FILENAME)
     Read the matrix X from a file.

     This function is equivalent to dlmread (FILENAME, "," , ...)

 -- Function File:  dmlwrite (FILE, A, "attrib1", VALUE1, "attrib2",
          VALUE2, ...)
 -- Function File:  dmlwrite (FILE, A, "-append", ...)
     Write the matrix A to the text FILE using delimiters.

    DELIM
          the delimiter to use to separate values on a row

    R
          the number of delimiter-only lines to add to the start of the
          file

    C
          the number of delimiters to prepend to each line of data.

    "-APPEND"
          append to the end of the FILE.

    "APPEND", STATE
          Either `"on"' or `"off"'.  See `"-append"' above.

    "DELIMITER", D
          See DELIM above.

    "NEWLINE", OS
          The character(s) to use to separate each row.  Three special
          cases exist for this option.  `"unix"' is changed into '\n',
          `"pc"' is changed into '\r\n', and `"mac"' is changed into
          '\r'.  Other values for this option are kept as is.

    "ROFFSET", R
          See R above.

    "COFFSET", C
          See C above.

    "PRECISION", P
          The precision to use when writing the file.  It can either be
          a format string (as used by fprintf) or a number of
          significant digits.

          A = reshape(1:16,4,4);
          dlmwrite(`"file.csv"', A)

          dlmwrite (`"file.tex"', A, "delimiter", "&", "newline", "\\n")

# name: <cell-element>

fexist
# name: <cell-element>
# type: string
# elements: 1
# length: 680
 -- Function File: ex = fexist (file, tspec, aspec)
     Checks whether a file exists.  FILE is the queried file path.
     TSPEC is a combination of letters f,d,p,S, corresponding to file
     types:
        * f: regular file

        * d: directory

        * p: named pipe (FIFO special file)

        * S: socket

     The query is true if the actual file type matches any of the
     specified options.

     ASPEC is a combination of letters r,w,x, corresponding to queried
     access privileges to the file. The query is true if the current
     user has all the spefied types of access, either through "user",
     "group" or "other" specs.

 XLSREAD reads EXCEL-files. 
 Currently, only a hack to read excel tables is implemented.  
 First, you need to convert your excel table into a tab-delimited 
 text file. Then you can use XLSREAD to load that file. 

  [NUM, STR] = XLSREAD(filename) 
      filename        tab-delimited text file
      NUM contains numeric data
      STR contains textual data
