Matlab crashes when plotting!

Here is a simple code to plot X,Y graph:
clear all; close all; fclose all; N=1000000; x=linspace(1,100,N); y=x.*x; plot(x,y,'o');
This program crashes Matlab when N is increased! But the same program runs if I have plot(x,y);
Any help? Thanks.

Please explain, what "crash" exactly mean: Do you get an error message?
You want to draw one million circles in a diagram? Beside the crash, do you assume that the resulting graphics could be useful to demonstrate anything?
Try to specify the renderer:
x = linspace(1, 100, 1e6);
y = x^2;
figure('Renderer', 'OpenGL');
opengl software
plot(x, y, 'o');
opengl hardware
plot(x, y, 'o');
figure('Renderer', 'ZBuffer');
plot(x, y, 'o');
figure('Renderer', 'Painters');
plot(x, y, 'o');
If only the OpenGL hardware method crashs, try to update the drivers of your graphics card.

Hi, I'm facing the same problem. Whenever I try to run the plot function, my Matlab (2014b) crashes. I even changed the graphics card settings to OpenGL with no luck.

Lets try to narrow down the issue.
Does this crash without the plot:
clear all
N=1000000;
x=linspace(1,100,N);
y=x.*x;
Or is it only with the plot?

Try changing the renderer as Jan mentioned.
figure('Renderer', 'Painters'); plot(x, y);
It that works, then restart matlab and run the following:
opengl software
That should resolve the issue.
