Hi,

Can you please post your code and the plot that you would expect the code to create? It is not clear what your objectives are? Are you using the optimization toolbox? Please provide us with more details.

Best Regards,

You question is somewhat unclear, but I will make an educated guess. Assuming the data looks like this:

IndexNum  = [ 1  2  5   9] ;
MinValues = [ 1  3  7  11] ;
MaxValues = [11 15 22  34] ;

You can make a plot connecting all MinValues and connecting all Maxvalues:

plot(IndexNum, MinValues ,'bo-',IndexNum, MaxValues,'rs-') ;

or you can make a plot connecting a MinValue to a MaxValue, for each index:

plot([IndexNum ; IndexNum],[MinValues ; MaxValues],'b^:')
