Hello, I have to vectors A(size 100) and D (size 100) and a matrix(100x100) in which I have all the value of a function T = f(A,D) for 100 value of A and 100 values of D. I plot a pcolor graph with :
pcolor(D,A,T)
and I'd like to draw an iso-line on this graph representing T = Tlim
Does anyone knows how to do that ?

hold on
contour(D, A, T, [Tlim Tlim]);
hold off
Using the same number twice is a "trick": if you had only given
contour(D, A, T, Tlim);
then it would try to interpret Tlim as the number of contours to draw.
