Hello,
You can try to acheive a similar result by using the "annotations" feature in MATLAB. The following code shows an example for plotting an ellipse and an arrow:
figure
x = linspace(-4,4);
y = x.^3 - 12*x;
plot(x,y)
dim = [.4 .55 .1 .25];
annotation('ellipse',dim)
annotation('arrow',[dim(1),dim(1)-dim(3)/2],[dim(2)+dim(4)/2,dim(2)+dim(4)/2])
The "dim" vector gives the the size and location of the smallest rectangle that encloses the ellipse. The dimensions of the arrow can also be defined separately as per requirement. The values are in normalized units. This can be changed by changing the "Units" property. Here is the link to the documentation for "annotations":
