class to store and retrieve persistent settings

Syntax

pref = swpref

pref = swpref('default')

Description

pref = swpref retrieves and creates a preference object.

pref = swpref('default') resets all preferences to default values.

The settings sotred in the swpref class for spinw objects will persist during a single Matlab session. It is different from the Matlab built-in preferences, as swpref resets all settings to factory default after every restart of Matlab.

Examples

We change the fontsize value and show that it is retained even when a new instance of the object is created:

pref = swpref
pref.fontsize

Output

    12

pref.fontsize = 18
pref2 = swpref
pref.fontsize

Output

    18

pref2.fontsize

Output

    18

Properties

Properties can be changed by directly assigning a new value to them. Once a new value to a given property is assigned, it will be retained until the end of a MATLAB session, even if a new class instance is created.

Methods

Methods are the different commands that require an swpref object as a first input, thus they can be called as method1(obj,...), alternatively the equivalent command is obj.method1(...).

Commands are methods which can be called without first creating a preference object swpref.command(....).
