Hi All,
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1103770/image.jpeg)
Could Anyone please help me ?
This is my code:
load matlab
lst = {'0.54','0.55','0.56','0.57','yline'}
plot(m4)
yline(0.1,LineWidth=1.5,LineStyle="--")
legend(lst)
Thanks and Regard!
Han

load matlab
lst = {'0.54','0.55','0.56','0.57','yline'}
plot(m4)
yline(0.1,LineWidth=1.5,LineStyle="--")
legend(lst)
for i=1:size(m4, 2)
F = griddedInterpolant(1:size(m4, 1), m4(:, i));
[~, x0] = min(abs(m4(:, i) - 0.1)); % coarse estimate
x(i) = fsolve(@(x) F(x)-0.1, x0); % finer solution
end
x
hold on
xline(x)
