You an use the following function to calculation intersection:

Tried it, but InterX is undefined variable or function is the error shown

You have to download that file from the above link. Read the help part of it. Make your curves and input these into the function. You must be in the same folder where the interX function is located. Or you have to add it into path.

The function works now, but i couldn't get to use the function properly. from my code i get blue curve, but i need to find the intersection of the blue curve with the black one(which is 0.98* of peak point of blue curve).

Attach the data of your curves in mat file here....
