Syntax

setpref(group, pref, val)

Stores val under pref in group, creating either if needed.

setpref(group, {pref1, pref2}, {val1, val2})

Sets several preferences at once.

Description

setpref is create-or-update: unlike addpref it does not complain when the preference exists. Read the value back with getpref.

Input arguments

group: Group name.
pref: Preference name or cell array of names.
val: Value of any type, or a cell array matching pref.

Example

Set one and several

setpref('demoapp', 'n', 3);
setpref('demoapp', 'n', 4);
setpref('demoapp', {'a', 'b'}, {1, 'two'});
disp(getpref('demoapp', 'n'))
s = getpref('demoapp')
rmpref('demoapp');

Output

     4
s = struct with fields:

    n: 4
    a: 1
    b: 'two'
