HOW TO WRITE THE FOLLOWING FUNCTION IN A MATLAB PROGRAM ? ALSO TELL THE WAY TO PLOT F(X)

F(X) =X , in (0,1) and F(X) =(X/2)+5 in (1,2)

[James Tursa]

What have you done so far? Have you written any code? Even an outline?

Answer 1

[Sara]

x = linspace(1e-6,2-1e-6,100);
f1 = x(x>0&x<1);
f2 = x(x>1&x<2)/2+5;

plot(x,[f1,f2])

[Jasmine]

Out of interest, what happens using this code if x is exactly 1?

[Sara]

I'll crash since x and [f1,f2] will be of different sizes. That's a cheap and easy solution to plot the function, not meant to represent all the occurrences. Can be modified as:

plot(x(x>0&x<2&x~=1),[f1,f2])
