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 HW8P3 (line 2)

r=linspace(0.001,1,1000);
s=0.75*((r.^3)./(exp(1).^(.75*r)));%error is here (multiplying by scalar does not need .*, but you need elementwise operations for matrix operations is needed)
