[Ifit-users] iFit bug :)

[Emmanuel FARHI]

Hello Sandor,

you indded found a bug when plotting final fit results from the 'output'
of 'fits'.
To solve it, add after line 39 of Libraries/Optimizers/fminplot.m, before
the 'else' keyword,

    [dummy, best] = sort(fvalHistory); % sort in ascending order
    best= best(1);

this should solve the problem.

An other way to plot the same thing is to use:

>> plot(a, output.modelValue)

Thanks for using iFit and reporting issues.

Emmanuel.
