If fyou are referring to ‘PWA’, try this (after your plot call):
for k = 1:size(PWA,1)
PWA0(k) = interp1(PWA(k,:), x, 0, 'linear', 'extrap');
fprintf('PWA = 0 at x = %4.2f\n', PWA0(k))
end
When I ran it, the result was:
PWA = 0 at x = 6.02
PWA = 0 at x = 7.47
PWA = 0 at x = 9.40
Experiment to get the result you want.
