But if you're only interested in plotting the periodic extension of x^2, then you can use the piecewise f(x) in the image above, which will be much more accurate than the Fourier series approximation F(x). Edited: Ned Gulley on 28 Oct 2013 I am trying to do a simple plot in matlab, how can I do this: a line that has a constant slope from y=0 to 40, then at 40 it is a flat line until infinity. syms x y = piecewise (x < 0,-1,x > 0,1) y = Evaluate y at -2, 0, and 2 by using subs to substitute for x. So the squared sum does not always equal 1. I can get it by plotting two separate graphs and by using the hold on capability. Viewed 132 times 0 I have the following code, which plots a line that crosses the origin. On the other hand, the function sin(1/x) is not piecewise continuous because it has infinite number of maxima and minima in the neighborhood of the origin. Ah, thanks. Plot the piecewise function. 0. (See PiecewiseExpand for an explanation of the option.) This does not even clean the local workspace, because there are no variables declared before. So you will basically type in the name of the function first and then type in the interval. Your functions can be combined into one well defined piecewise function, In the following {0,True) assigns the value zero to the function outside the defined intervals: pw [x_] := Piecewise [ { {2 x - 3 , -4 <= x <= 1}, {-7 x + 2 , 1 < x <= 5}, {0,True}}] You can plot this (as desired).
