    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。 y-gSal  
    :[oFe/1K!4  
    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: L<encPJt  
    enableservice('AutomationServer', true) F'DO46  
    enableservice('AutomationServer') 0!YB.=\{_q  
    xJ)hGPrAl  
    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 GpV"KVJJ/  
     q[#2`  
    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: #8G (r9  
    1. 在FRED脚本编辑界面找到参考. ~{hcJ:bI  
    2. 找到Matlab Automation Server Type Library /pZ]:.A  
    3. 将名字改为MLAPP r7r>1W%4

    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。 Z> jk\[

    1. 创建Matlab服务器。 y~CK&[H  
    2. 移动探测面对于前一聚焦面的位置。 !%<bLD8  
    3. 在探测面追迹光线 hiWfVz{~  
    4. 在探测面计算照度 E(F<shT#  
    5. 使用PutWorkspaceData发送照度数据到Matlab V )CS,w  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :!a'N3o>  
    7. 用Matlab画出照度数据 C~IsYdln
