Plotting y=x Function in Matlab: Tips for Beginners

djdato · Apr 4, 2009

I am new to Matlab and i need to plot a function. However, using y=x as an example it always comes up saying that x is not defined. How do i plot the function without specifying a specific value for x? Graphing y=x is not my real problem. I am used to using TI-83/4 graphics calculators and typing a function like y=x^2 and just graphing it. But i can't do it on MATLAB as it always needs me to define x.
