    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。 _2KIe(,;  
    )\])?q61  
    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: @x `X|>&  
    enableservice('AutomationServer', true) tE %g)hL-  
    enableservice('AutomationServer') d==0 @`  
    l]G iz&  
    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 QC'Ru'8S  
    ;R= n<=Axa  
    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: (iKJ~bJ  
    1. 在FRED脚本编辑界面找到参考. xLed];2G  
    2. 找到Matlab Automation Server Type Library S(@kdL  
    3. 将名字改为MLAPP |GMo"[  
    iM!Ya!  
    ")KqPD6k  
    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。 V u")%(ix

    1. 创建Matlab服务器。 aEdA'>  
    2. 移动探测面对于前一聚焦面的位置。 K/9Jx(I,qL  
    3. 在探测面追迹光线 4prJ!k  
    4. 在探测面计算照度 nlpEkq  
    5. 使用PutWorkspaceData发送照度数据到Matlab pZ8J\4+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [~Ky{:@)[  
    7. 用Matlab画出照度数据 \MEBQ  
    8. 在Matlab计算照度平均值 !4Aj#`)  
    9. 返回数据到FRED中 _1[Wv?
