最小方差无畸变波束形成，常用的常规波束形成方法(Minimum variance distortionless beam forming, common conventional beamforming method)

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.

自己写的Floyd,没有理解Folyd的同学可以拿去参考一下啦!!!!(Wrote it myself Floyd, do not understand Folyd students can refer to you instead!!!!)
