Set the internal search path to the result and return it. See also: addpath , rmpath , genpath , pathdef , savepath , pathsep. The path information is extracted from one of four sources.

The possible sources, in order of preference, are:. See also: path , addpath , rmpath , genpath , savepath. Return the absolute name of file if it can be found in the list of directories specified by path. In this case, if file exists it will be returned in fname , otherwise an empty string is returned. If the first argument is a cell array of strings, search each directory of the loadpath for element of the cell array and return the first that matches.

To get the name of this and all other environment variables, type "who". For instructions on how to open a data file, see Basic Reading and Writing data from a file. Octave for Windows retains the file naming constraints set by DOS. The following characters cannot be used in filenames:. When you declare an m-file function, the m-file must be the same name as the function or Octave will not be able to run it.

So for example if you declare a function 'factorial' as:. This works equally on files that are compressed with gzip outside of octave, and gzip can equally be used to convert the files for backward compatibility. This option is only available if Octave was built with a link to the zlib libraries.

The list of variables to save may use wildcard patterns containing the following special characters:. Match the list of characters specified by list. If the first character is! For example, the pattern [a-zA-Z] will match all lower and uppercase alphabetic characters. Wildcards may also be used in the field name specifications when using the -struct modifier but not in the struct name itself.

Query or set the internal variable that specifies the default options for the save command, and defines the default format. Typical values include "-ascii" , "-text -zip".

The default value is -text. When called from inside a function with the "local" option, the variable is changed locally for the function and any subroutines it calls. The original variable value is restored when exiting the function. Query or set the internal variable that specifies the number of digits to keep when saving data in text format. Query or set the internal variable that specifies the format string used for the comment line written at the beginning of text-format data files saved by Octave.

The default value is. See also: strftime , save. If no variables are specified then all variables found in the file will be loaded.

As with save , the list of variables to extract can be full names or use a pattern syntax. The format of the file is automatically detected but may be overridden by supplying the appropriate option.

If a variable that is not marked as global is loaded from a file when a global symbol with the same name already exists, it is loaded in the global symbol table.

Also, if a variable is marked as global in a file and a local symbol exists, the local symbol is moved to the global symbol table and given the value from the file. If invoked with a single output argument, Octave returns data instead of inserting variables in the symbol table. If the data file contains only numbers TAB- or space-delimited columns , a matrix of values is returned.
