fzero-funtion in 20112b

Using the “parametric ROC curve script developed by L. Bantis, I recocnized that the fzero function is not accessible in 2012a and 2012b (maybe the function is shifted in the optimization toolbox). Any solution? Thanks

No, fzero probably isn't the cause of the problem. I don't have the Optimization Toolbox and I can do the following easily in R2012a,

   >> fzero(@(x)x-1,2)

    ans =

         1

which -all fzero

If nothing comes back, restore the default path and rehash the toolbox cache:

restoredefaultpath
rehash toolboxcache

Thanks, it works

restoredefaultpath rehash toolboxcache
