Create a MATLAB function m file, drawcircle() that contains the following elements

a. Three input values in this order r, xc, yc, color i. r is the radius of the circle ii. xc is the x coordinate of the center iii. yc is the y coordinate of the center iv. color is the color and line style of the line to be drawn

b. Hint create an internal variable theta that is a vector of 101 angle values on the interval [0,2] . Note that the x and y locations for a point on the circle are related to the radius and either the cosine or sine of the angle theta. Be careful to consider the location of the center of the circle and plotting a + to indicate the location.
