我用slove求解方程，出错了。
Warning: Explicit solution could not be found.
> In solve at 140
In sym.solve at 49
S =
[ empty sym ]
??? Error using ==> reshape
To RESHAPE the number of elements must not change.
Error in ==> sym.maple at 94
result = reshape(result,size(varargin{3}));
Error in ==> sym.sin at 7
Y = maple('map','sin',X);
怎么回事呢？
