Set preference

Syntax

setpref('group','pref',val)
setpref('group',{'pref1','pref2',...,'prefn'},{val1,val2,...,valn})

Description

setpref('group','pref',val)sets the preference specified bygroupandprefto the valueval. Individual preference values can be any MATLAB®data type, including numeric types, character vectors, cell arrays, structures, and objects. Setting a preference that does not yet exist causes it to be created.

grouplabels a related collection of preferences. You can choose any name that is a legal variable name, and is descriptive enough to be unique, e.g.,'MathWorks_GUIDE_ApplicationPrefs'. The input argumentprefidentifies an individual preference in that group, and must be a legal variable name.

setpref('group',{'pref1','pref2',...,'prefn'},{val1,val2,...,valn})sets each preference specified in the cell array of names to the corresponding value.

Note

Preference values are persistent and maintain their values between MATLAB sessions. Where they are stored is system dependent.

Examples

Useaddprefto create a preference group calledmytoolboxand a preference within it calledversion, and then modify the contents ofversionusingsetpref:

addpref(“mytoolbox”、“版本”,“1.0”)getpref(“mytoolbox','version') ans = 1.0 setpref('mytoolbox','version',{'1.0','beta'}) getpref('mytoolbox','version') ans = '1.0' 'beta'
