I have the graph shown below, i want to find the point on the y axis where the red line (at a known value of x 'N(1)') intercepts the blue curve, but I keep getting an error that says "Error using matlab.internal.math.interp1, Sample points must be unique."
N= length(Kr);
Nn= zeros(N,1)+sr;
hold on
plot(Nn,Kr,"--","linewidth",2)
xlabel("Sr")
ylabel("Kr")
title("R6 Envelope")
X= interp1(s, K, Nn(1))
How can I fix this? Thanks
