Find the Minimum and Maximun of ListDensityPlot in Mathematica

Question

I have a set of data points, lets say {x_i,y_i,A_i}. I want to find the Minimum and Maximum value of A_i from a ListDensityPlot in Mathematica. Along with the corresponding x_i & y_i values.

Rupesh · Answer

Use Max and Min:

f[x_] := x^2 + y^2
    data = Table[{x, y, f[x]}, {x, -5, 5, .1}, {y, -5, 5, .1}]
    datamax = Max[Map[#[[3]] &, Flatten[data, 1]]]
    datamin = Min[Map[#[[3]] &, Flatten[data, 1]]]
