Plotting Error (Very Simple Code)

As part of practice of plotting, I made a very simple code, but it has an error. Would you check the code and explain on the problem so that I can make an correction?

x=1.0:0.2:2.0; y=2/x; plot(x,y)

Error using / Matrix dimensions must agree.

Error in Untitled6 (line 2) y=2/x;

Answer 1

y = 2./x;

The operation A/B is like A * inv(B) where * is algebraic matrix multiplication. You want element-by-element division, which is the ./ operator

It works! Thank you so much.
