Save plot to a matrix in Octave/MatLab

Question

I wish to save a plot created in octave in a matrix

x=[0:10];
y=[0:10];
figure(1);
plot(x,y);

How can I save this plot into a matrix (or a 3D array, assuming it is RGB). To explain in a different way. Lets say there exist an image "img.jpg" in the working directory. Than i can open it as a matrix

A=imread("img.jpg");

How can one accomplish the same, having the plot saved in the matrix A?

Answer 1

Did you mean loading an image stored as a matrix into a variable? If so, You can use A = load('img.mat')
