全息谱的matlab程序运行出错求助

程序中的PIP2.DH与PIP2.DV为输入数据，但运行程序出错，出错程序为这一句
function =holo2D('PIP2.DH','PIP2.DV',2000,45,0)

系统会出现下面的文字
??? Error: File: C:\Documents and Settings\Administrator\桌面\实验\holo2D.m Line: 10 Column: 30
"identifier" expected, "character string" found.
意思就是在第10行30列出错，在那个位置是一个单引号'      
我把程序和输入数据放在附件里，希望各位高手帮我看一下到底哪里出错了，这是我论文要的东西，很急
谢谢各位了！

请问这句是什么意思？
function =holo2D('PIP2.DH','PIP2.DV',2000,45,0)
如果是传递PIP2.DH和PIP2.DV文件中的数据，可以考虑先读出数据，再传递

程序可以这样贴上来，方便别人查看

另外，function =holo2D('PIP2.DH','PIP2.DV',2000,45,0)
里面参数根本没有传进去
