Hello, I have data for optimization that contains different values of 4 different parameters, and the respective function value based on them. I want to find the maximum of this function, while making sure it's a "stable" maximum, i.e., for nearby parameters, the value of the function shouldn't change that much. My only question is what tool to use for this, since I have 60k values in total? I have experience in Matlab, can that be done in a reasonable amount of time there? I also have some basic knowledge of R, and can learn fast anyway, is this more suitable to do in R? Thanks!
