Yalmip suddenly unable to work

[ran tao]

i always use yalmip to solve some problem

bu a code without any modify suddenly unable to work

so i reinstall yalmip, and run the 'yalmiptest'

and some mistake as following

>> yalmiptest

No function or variable defined 'strmatch_octavesafe'。

Error sdpsettings (line 303)

        j = strmatch_octavesafe(lowArg,names);

Error yalmiptest (line 112)

    ops = sdpsettings('Solver',prefered_solver);

Well, then you must have installed something incorrectly

>> which strmatch_octavesafe

C:\work\yalmip\extras\strmatch_octavesafe.m

>> which sdpsettings

C:\work\yalmip\extras\sdpsettings.m

strmatch_octavesafe is in master as expected
