Too many input arguments while plotting

x=[1:10];

y=[10:20];

plot(x,y)

Error using plot

Too many input arguments. What's the mistake? My friends can plot it easily.

[Star Strider]

Your friends most likely do not have a variable or user-created function called plot.

To find the one on your computer, run this line from a script or your Command Window:

which plot -all

That will tell you where it is so you can change its name to something that does not overshadow any MATLAB functions.

While I agree with Star Strider based on the error that you provided, it should also be noted that both the x and y vectors must be the same length. Your example has an x-variable with size 1x10 and a y-variable with size 1x11. Try:

x = 1:10;
y = 11:20;
% or
x = 1:11;
y = 10:20;
