各位大神，有时间帮小弟看看一个问题，交流技术，学习！

matlab转java文件后，在java端访问报了个错如下：
{??? Error using ==> boiler_process at 134
X must be a matrix or a row cell array

Error in ==> mapminmax at 71



Error in ==> prediction at 16


}
... Matlab M-code Stack Trace ...

不知是何意思？对matlab不熟，懂的大牛帮忙看一下。我java在跑matlab的a和b的加法运算是可以成功，现在这个错是java跑matlab另一个精密算法时出现的。先谢谢了
