The comment line written at the beginning of text-format data files saved by Query or set the internal variable that specifies the format string used for : val = save_header_format_string () ¶ : old_val = save_header_format_string ( new_val) ¶ : old_val = save_header_format_string ( new_val, "local") ¶ If file size is a concern, it is probably better to choose aīinary format for saving data rather than to reduce the precision of the saved The default value is 17 which is the minimum necessary for the lossless savingĪnd restoring of IEEE-754 double values For IEEE-754 single values the minimum Query or set the internal variable that specifies the number of digits to : val = save_precision () ¶ : old_val = save_precision ( new_val) ¶ : old_val = save_precision ( new_val, "local") ¶ See also: save, save_header_format_string, save_precision. The original variable value is restored when exiting the function. Variable is changed locally for the function and any subroutines it calls. When called from inside a function with the "local" option, the See the documentation of the save command for other choices. The default value is "-text" (Octave’s own text-based file format). Query or set the internal variable that specifies the default optionsįor the save command, and defines the default format. : val = save_default_options () ¶ : old_val = save_default_options ( new_val) ¶ : old_val = save_default_options ( new_val, "local") ¶ There are three functions that modify the behavior of save. See also: load, save_default_options, save_header_format_string, save_precision, dlmread, csvread, fread. Saves the variable ‘ a’ and all variables beginning with ‘ b’ to the If the variable is restored at a later time using ‘ load’, it will be struct modifier (but not in the struct name itself).Įxcept when using the MATLAB binary data file format or the ‘ -ascii’įormat, saving global variables also saves the global status of the variable.
Wildcards may also be used in the field name specifications when using the
For example, the pattern will match all lower and Is ! or ^, match all characters except those specified by Match the list of characters specified by list. The list of variables to save may use wildcard patterns (glob patterns)Ĭontaining the following special characters: Was built with a link to the zlib libraries.
