How can i create a function that returns the x and y coordinate of a circle with given center, radius an interval from 0 to 2*pi?

How can i create a function that returns the x and y coordinate of a circle with given center, radius an interval from 0 to 2*pi?

Use trigonometry: cos() and sin()

[Özgür Saglam]

function [x,y] = getCircle(xm,ym,radius)
%UNTITLED4 Summary of this function goes here
%   Detailed explanation goes here
t = (0:1:2*pi);
x = radius*cos(t)+xm;
y = radius*sin(t)+ym;
end

I tried this but when i write A = (3,3,3) for example i just get a 1x8 matrix. Instead of this i want two values, one for x and another one for y

Those are fairly big steps. You should probably look into the linspace function.

And how exactly are you calling this function?

[Özgür Saglam]

Yeah i know the linspace function but i dont know how i should integrate it in my function

Look at how you are generating the t vector. That would be a way to make your circle look a lot more like a circle.

Hi,

According to your comments I think you just want a particular point (x,y co-ordinates) on a circle. For that you should also pass the angle value too. You got the function almost right, I have modified it a little:

function [x,y] = getCircle(xm,ym,radius,t)

x = radius*cos(t)+xm;
y = radius*sin(t)+ym;
end

where t can lie between the interval [0,2*pi] in radians.

Hope this helps!

Personally I think it is more likely that OP was calling the function with a single output and should increase the number of angles.

It looks like homework to me, and I don't see how it makes sense to ask for a part of the arc in a homework question.
