Question

Write a function called calc_crown_area that will receive pairs of lengths of radii as input arguments, and will return the areas of the crowns. The function should work when: • the inputs are a pair of single values, i.e. one scalar for the inner radius and one scalar for the outer radius. In this case, the function will return one single output for the area. • the inputs are a pair of vectors, i.e. one vector of inner radii (R1) and a corresponding vector of outer radii (R2), of the same length n. In this case the function will return n values for the areas where each is calculated as  * (R2i2 – R1i2) for each i ≤ n. For this case, your code needs to handle the user error when the two vectors provided as inputs do not have the same length. • your code needs to handle the user error when r1 > r2 for both scalar and vector inputs. (pls answer it in Matlab)

Answer 1

function area = calc_crown_area(r1,r2)
if length(r1)~=length(r2)
error('Length of r1 and r2 must be same!!!')
end
if any(r1>r2)
error('r1 must be smaller than r2')
end
area=pi*(r2.^2-r1.^2);
