用matlab来做一个三维模型，包括两个部分： 1.长方体 2.很多个半径（远小于长方体边）很小的球体随机分布在长方体中。(Using MATLAB to make a three-dimensional model, including two parts: 1. a rectangular cube with a lot of radius (which is far smaller than the side of a rectangular body) and a small sphere is randomly distributed in a rectangular body.)

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息，导致了接收信息在某种意义上的浪费。软判决将接收电平量化，尽可能保存相应的信息，故可以提高译码性能。(soft descision decoding)

roots -Polynomial roots Syntax r = roots(c) Description r = roots(c) returns a column vector whose elements are the roots of the polynomial c. Row vector c contains the coefficients of a polynomial, ordered in descending powers. If c has n+1 components, the polynomial it represents is . Tips Note the relationship of this function to p = poly(r), which returns a row vector whose elements are the coefficients of the polynomial. For vectors,roots and poly are inverse functions of each other, up to ordering, scaling, and roundoff error.
