    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。 CLZ j=J2  
    n~ $S  
    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: cXt&k  
    enableservice('AutomationServer', true) !nL94:8U  
    enableservice('AutomationServer') TD floDxA  
    d~_5Jx  
    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 :j3^p8]

    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: EP;ts  
    1. 在FRED脚本编辑界面找到参考. B>'J5bZsw  
    2. 找到Matlab Automation Server Type Library #O~pf[[L  
    3. 将名字改为MLAPP k>MXOUaW.

    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。 s \3]0n9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ! 1?u0  
    1. 创建Matlab服务器。 p cUccQ  
    2. 移动探测面对于前一聚焦面的位置。 r UZN$="N  
    3. 在探测面追迹光线 ?$;&DoE  
    4. 在探测面计算照度 m,hqq%qz  
    5. 使用PutWorkspaceData发送照度数据到Matlab Xo(W\Pes  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xzz@Wc^_  
    7. 用Matlab画出照度数据 o6 NmDv5  
    8. 在Matlab计算照度平均值 SZ4y\I  
    9. 返回数据到FRED中 ;7E"@b,tPN
