How to find the maximum deviation between x-values, given one y-value on a plot.

I want to find the maximum difference between x-values (Temperature) between both curves. The same temperature variable is used for both curves to calculate Output Voltage at 0:1:100.

For instance, I want to find the Output Voltage that produces the maximum temperature difference. I want to print that Voltage and the respective temperature values from each curve for that y-value, on the screen.

Thanks.

Perhaps as follows,

F1=griddedInterpolant(OutputVoltage1, Temperature);
F2=griddedInterpolant(OutputVoltage2, Temperature);

Vmax=fminbnd(@(V) -abs(F1(V)-F2(V)), 0 ,100)

Temperature1=F1(Vmax)
Temperature2=F2(Vmax)
