    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 ?Sn$AS I  
    zi-zg Lx  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: &r~~1BnpHm  
    enableservice('AutomationServer', true) jt Q2vJ-  
    enableservice('AutomationServer') 6x*ImhQ.J  
    XLqS{r~?  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 f@\ k_  
    Z>o;Yf[  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: L9fhe,en  
    1. 在FRED脚本编辑界面找到参考. 75!IzJG  
    2. 找到Matlab Automation Server Type Library b[GZ sXD-  
    3. 将名字改为MLAPP v}xz`]MW<,

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 T-fW[][&$

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ptb t  
    1. 创建Matlab服务器。 o6xl,T%  
    2. 移动探测面对于前一聚焦面的位置。 hrU.QF8  
    3. 在探测面追迹光线 ORcl=Eo>  
    4. 在探测面计算照度 Z=8 25[p  
    5. 使用PutWorkspaceData发送照度数据到Matlab e`k 2g ^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 hP3I_I[qF}  
    7. 用Matlab画出照度数据 k-e_lSYk&c  
    8. 在Matlab计算照度平均值 J24UUZ9&$  
    9. 返回数据到FRED中 MCL?J,1?r
