I know that non of the parameters are negative and D is less than 1. you got the formula right. p.s. this is part of an optimization problem for a generator design, so I know the amount of parameters approximately but I need to know in which range I could change them to earn optimize result.

Hi everybody. I want to find suitable range for four parameters: x(1), x(2), x(3) and x(4); in a way that: 326.705<x(1)*x(2)*(1+x(4))^2*(1-x(4))*x(3)^3<378.29 What should i do? Is there any way to find the answer by MATLAB?
