请高手指点迷津：红色部分的代码为什么错了？怎样修改？

Error in ==> ..\linlagex\matrix_function.m
On line 23==> eval(sprintf('eval([''%s_j=@(%s)%s;''])',char(matj),it_name,target))

这是matlab的提示。

M文件在附件中。

我要对货币政策的模型进行数值模拟。模型中要求解前瞻性变量，我找到求解的代码(这仅仅是求解文件中的一个），但是运行的时候总是出错。我对matlab了解不是很多，但是这些模型深刻而完美地体现了经济运行规律，我必须对它们求解。技术问题，一个难关，很是头痛。

为了使问题更加清楚，我把求解程序包附上，而且附上一个例子。请高手告诉我，究竟什么地方出错啊？怎样改正？
