How to find the maximum value of the below curve:
z1 = [0.00008 0.009]';
a11 = -4:0.001:4;
k1 = (atan(((0.01/2 + a11)./z1) + atan((0.01/2 - a11)./z1)));
plot(a11,k1(1,:),'-k',a11,k1(2,:),'-r')

Hi @Amy Topaz
Since the curves are arctangent functions, the max values can be found at the boundary, in this case, that is a11 = 4.
It is important to know that the limit at infinity of the arctangent function is
.

max_idx = length(a11)
k11_max = k1(1,:)(max_idx)
k12_max = k1(2,:)(max_idx)
k11_max = 1.5708
k12_max = 1.5685
