hi how can i evaluate the function below from x=1,x=2 into a step of 0.1 y=x/(x2+1)
x = 1:0.1:2; % Define the range of x with a step of 0.1 y = x./(x.^2 + 1); % Evaluate the function plot(x,y)

Why dot indexing is not supported for variables of this type using EMD method in MATLAB R2019a version ? What can I do?
It seems IMF is not a sturcutre. Check class(IMF) If it is double. Try max(IMF)
