Using while loop in a function?

Hello! First of all thank you for helping me out, this forum has done a lot to teach me more about MatLab.

I have a function that rotates a shape on a plot by however many degrees is inputted, which looks like this:

function [newx newy] = rotate(xcoords, ycoords, angle)
angle = angle*(pi/180);        % convert angle to radians
newx = xcoords*cos(angle) - ycoords*sin(angle);
newy = xcoords*sin(angle) + ycoords*cos(angle);

I'm trying to write a second function with this function (we'll call rotate) with a while loop, but it does not seem to be working. What I want to do is when there is an input of x coordinates, y coordinates, and a number (which I assigned to repeats), it plots the specified number of rotations on a graph.

function [xc1, xc2] = spin(xcoords1, ycoords1,repeats)

degreeangle = 360/repeats;
hold on
while repeats > 1
    [xc1, xc2] = rotate(xcoords1,ycoords1,degreeangle);
    plot(xcoords1,ycoords1,'b-')
end 
hold off

I am not sure why my code isn't working. Would appreciate any help! Thank you!

function spin(xcoords1, ycoords1,repeats)
degreeangle = 360/repeats;
hold on
while repeats > 1
    [xcoords1, ycoords1] = rotate(xcoords1,ycoords1,degreeangle);
    plot(xcoords1,ycoords1,'b-')
    repeats=repeats-1;
end 
hold off
