Need help with sensitivity analysis tool

Hi,

This is my model structure

Pressure - calculating flowrates and pressures using balance equations and fsolve

VRFB file - calculating value of shuntcurrent losses using matrix and get value of shunt current energy loss

- calling fsolver on Pressure file and getting values to calculate pressure energy losses

main - calling VRFB calculated value of these two outputs and setting paramaters

- using loop where I change one parameter p1 and look for the optimal value of parameter p1, where is the minimal value of these two energy losses combined together

My goal is

-create sensitivity analysis for this loop, where I could set min and max of other parameters (let say - p2 - temperature - min 10 max 40, p3- density min 1000 max 1500) and see, how the optimal parameter p1 changes for these min max p2, p3

Is there any tool in matlab for this or anyone knows code for thiss?

Thank you

Martin
