    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。 ay| |yn:  
    {; th~[  
    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: ,`OQAJ)>  
    enableservice('AutomationServer', true) SSbx[<E3  
    enableservice('AutomationServer') ,j9?9Z7R  
    ,jtaTG.>  
    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 ,L.V>Ae  
    `KE]RTq  
    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: @ULWVS#t2  
    1. 在FRED脚本编辑界面找到参考. yTn<5T[H  
    2. 找到Matlab Automation Server Type Library )m[<lJ bw  
    3. 将名字改为MLAPP h@'CmIZc

    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。 WbBd<^Q

    现在将脚本代码公布如下,此脚本执行如下几个步骤: e ky1}  
    1. 创建Matlab服务器。 l!KPgRw  
    2. 移动探测面对于前一聚焦面的位置。 )v11j.D  
    3. 在探测面追迹光线 B[6k [Vs  
    4. 在探测面计算照度 #D%6b  
    5. 使用PutWorkspaceData发送照度数据到Matlab U* c'xoP  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Wv9L }@J  
    7. 用Matlab画出照度数据 &cJ?mSI  
    8. 在Matlab计算照度平均值 ~'0ZW<X.  
    9. 返回数据到FRED中 Lz p}<B
