    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。 saD-D2oj  
    xmGk*W)P  
    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: h O emt  
    enableservice('AutomationServer', true) E| :!Q8"%w  
    enableservice('AutomationServer') ZX~ _g@  
    US{3pkr;I]  
    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 Npn=cLC&  
    ,%YBG1E[y  
    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: vVT?h  
    1. 在FRED脚本编辑界面找到参考. ftBq^tC  
    2. 找到Matlab Automation Server Type Library V,EF'-F  
    3. 将名字改为MLAPP wve=.n

    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。 _#o' +_Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: amQz^^  
    1. 创建Matlab服务器。 0uCT+-  
    2. 移动探测面对于前一聚焦面的位置。 UK*qKj. )  
    3. 在探测面追迹光线 9N[EZhW  
    4. 在探测面计算照度 xv7"WFb  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9j*0D("  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "8V{5e!%j'  
    7. 用Matlab画出照度数据 K t#,]]  
    8. 在Matlab计算照度平均值 z&4~x!-_  
    9. 返回数据到FRED中 x?D/.vrOY
