从提示看，你程序中某个算式中含有sym字符，你却要用double命令转成数值，这是转换不了的，就会有这样的提示。请看清提示是哪一行代码有错，针对这行代码查找下问题，再改正。
Unable to convert expression into double array. Error in sym/double (line 661) Xstr = mupadmex('symobj::double', S.s, 0); I could not execute the code, as M1 and E1 are not provided. Maybe the error jumps before the lines that I marked. If so, do the same comprobation, check...
