I am working on edge detection algorithms and i need to produce matrices which cointain graphs of various functions. They need to be in black-white format (no RGB three layer matrices).
For example if i use linspace and build up the graph of y=x^2 how do i save the plot in a non RGB matrix ?

x = linspace(-5,5,100);
y = x.^2;
plot(x,y)
fr=getframe(gca);
gray_image=im2gray(fr.cdata);
