ispref

Determine if custom setting exists

Syntax

ispref(group,pref)

ispref(group)

Description

ispref(group,pref) returns 1 if the specified setting in the specified group exists, and 0 otherwise. If pref specifies multiple settings, ispref returns a logical array containing a 1 or 0 for each specified setting.

ispref(group) returns 1 if the specified group exists, and 0 otherwise.

Examples

Check If Setting Exists

Add a setting called version to the mytoolbox group of settings and then check if the setting exists.

addpref('mytoolbox','version','1.0')
ispref('mytoolbox','version')

ans =
  logical
   1

Check If Multiple Settings Exist

Add two settings to the mytoolbox group of settings and then check if the settings exist.

addpref('mytoolbox',{'modifieddate','docpath'},{'1/9/2019','C:\mytoolbox\documentation'})
ispref('mytoolbox',{'modifieddate','docpath','hasdoc'})

ans =
  1×3 logical array
   1   1   0

MATLAB^® returns a logical array containing a 1 for the modifieddate setting and a 1 for the docpath setting. The hasdoc setting does not exist and therefore the last value of the logical array is 0.
