### Test Suite

Test Status Code Input and Output
1   Pass
H = 1; y_correct = sqrt(2) - 1; assert(isequal(view_factor(H),y_correct))

2   Pass
H = 3; y_correct = sqrt(10) - 3; assert(isequal(view_factor(H),y_correct))

3   Fail
H = [0.5 2 4 10]; y_correct = [sqrt(1.25)-0.5, sqrt(5)-2, sqrt(17)-4, sqrt(101)-10]; assert(isequal(view_factor(H),y_correct))

Error using ^ (line 51) Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power is a scalar. To perform elementwise matrix powers, use '.^'. Error in view_factor (line 2) F = sqrt(1+H^2)-H; Error in Test3 (line 3) assert(isequal(view_factor(H),y_correct))
