| Actually, no it doesn't mean that the Optimization Toolbox is not available. Several others have asked about this and here is a copy of my response ...
The test failures are because fmincon's interior-point method (which is now the default, i.e. MATPOWER option ' FMC_ALG' is now 4 instead of 1) was not accurate enough in Matlab versions 7.6-7.9. So if you plan to use fmincon for running optimal power flows ( OPF_ALG = 520), I suggest you limit yourself to using the active-set method ( FMC_ALG = 1).
I have attached an updated version of t_opf_fmincon.m that uses the active-set method for fmincon for the tests under those versions of Matlab.

I am just starting to use the matpower software.
When I type the 'test_matpower' at the matlab prompt, I get the list below. As
you might observe, it reports that "t_opf_fmnincon" is not ok. Does it mean
that matpower is not installed successfully?
Kind regards,
