how to plot a defined space?

F11*x^2 + F22*y^2 + F1*x + F2*y + 2*F12*x*y >= 1

I need to graphically represent the above equation over a given domain, all of the F terms are constants (this is the Tsai-Wu criteria for composite laminates)

what function would i use to plot this?

Do you have to compute it for every value of x and y in a rectangular area? If so, you can use a for loop or meshgrid(), then compute the value "z" or "imageArray" for every value of x and y, then use image() or imshow() to display it. Or you could use surf() to display it as a 2.5D perspective rendering.
