    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。 rElG7[+)p  
    ^v()iF !  
    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: w+:+r/!g  
    enableservice('AutomationServer', true) l%vhV&  
    enableservice('AutomationServer') p;)klH@X  
    9}7oKlyk  
    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 ZVCv(J  
    5k!(#@a_T  
    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: kr &:;  
    1. 在FRED脚本编辑界面找到参考. D(W7O>5vQ2  
    2. 找到Matlab Automation Server Type Library KV3+}k  
    3. 将名字改为MLAPP |wl")|b%

    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。 J{v6DYhi

    1. 创建Matlab服务器。 6Wcn(h8%*  
    2. 移动探测面对于前一聚焦面的位置。 (rCPr,@0  
    3. 在探测面追迹光线 ?j ;,q  
    4. 在探测面计算照度 [9##Kb  
    5. 使用PutWorkspaceData发送照度数据到Matlab w^vK7Z 1$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `jl. f  
    7. 用Matlab画出照度数据 _'o^@v:
