This is my first time using MATLAB to call eclipse to calculate gradient and sensitivity w.r.p.t permeability since I want to estimate permeability distribution of an oil-water reservoir. My problems are:

(1) which keyword control output of gradient ? how do I put that keyword into data file?

(2) which keyword control output of sensitivity? From which files I can extract the sensitivity result?

I already know that how to write required files before running eclipse. But above two problems really give me a headache since I have no idea about how to include those two keyword in RUNSPEC and others sections. You kind help will be highly appreciated.
