According to the note at the bottom of the documentation page this function was introduced in release R2016a. I suspect you're using an earlier release of Symbolic Math Toolbox.

subs() in all of the vectors at the same time. vpa() or double() the result.

在 MATLAB Online 中打开

subs() is working with 2 vectors at a time, else giving the error.

Gp=subs(Gp,[Gxy,thi,thj],[G,thi1,thj1]);
Error using sym/cat>checkDimensions (line 75)
CAT arguments dimensions are not consistent.
Error in sym/cat>catMany (line 38)
[resz, ranges] = checkDimensions(sz,dim);
Error in sym/cat (line 27)
    ySym = catMany(dim, strs);
Error in sym/horzcat (line 19)
    ySym = cat(2,args{:});
