find the gradient by using laplacian

hello all, i have a graph that i wanted to calculate the steepest slope on each descending part of the curve. I did it. But i want to confirm that for sure that is the point with the biggest slope. so i want to use the laplacian mode. can anyone help me how im gonna do that?

It looks like you're already finding the slopes. So just find them all in a for loop and keep track of which is the biggest.

I would use the gradient function, if you haven’t already.

See if the del2 function will do what you want.

i already did that. i need to use the lapacian in order to confirm that.
