本人在用matlab做空间杜宾模型，用的是jplv7工具箱做的，但是结果却提示输出参数过多，请问我应该怎么做，代码如下！（还有matlab只需要把面板数据设置成要求的格式就行么，没有其他的要求了，怎么能保证空间权重矩阵和自变量矩阵相乘的时候不会出现问题，希望大神们帮我解答一下，谢谢）
results = sdm(y,X,W,info)
PURPOSE: computes spatial durbin model estimates
          (1-rho*W)y = a + X*B1 + W*X*B2 + e, using sparse algorithms
  ---------------------------------------------------
   USAGE: results = sdm(y,x,W,info)
   where: y = dependent variable vector
          x = independent variables matrix
          W = contiguity matrix (standardized)
        info = an (optional) structure variable with input options:
        info.rmin = (optional) minimum value of rho to use in search  
        info.rmax = (optional) maximum value of rho to use in search   
        info.convg = (optional) convergence criterion (default = 1e-8)
        info.maxit = (optional) maximum # of iterations (default = 500)
        info.lflag = 0 for full lndet computation (default = 1, fastest)
                   = 1 for MC lndet approximation (fast for very large problems)
                   = 2 for Spline lndet approximation (medium speed)
        info.order = order to use with info.lflag = 1 option (default = 50)
        info.iter  = iterations to use with info.lflag = 1 option (default = 30)
        info.lndet = a matrix returned by sar, sar_g, sarp_g, etc.
                     containing log-determinant information to save time
错误使用 info
输出参数太多。
