Hey guys.. I'm new in Matlab and this is my first week of using it, and our teacher already gave us homeworks. He didn't show us anything, just something about matrix.

Please, how can I plot center(5,7) and radius 3? I've tried this:

function circleplot(xc, yc, r) 
t = 0 : .1 : 2*pi; 
x = r * cos(t) + xc; 
y = r * sin(t) + yc; 
plot(x, y) 
axis square; grid

and called it like this:

xc = 5; 
yc = 7; 
r = 3; 
circleplot(xc, yc, r)

Gives me error: | Undefined function 'circleplot' for input arguments of type 'double'. |

Your code is correct, check if your function is saved in the current folder

Man I forgot that my teacher wanted a SCRIPT to make this. What is the code for script?
