    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。 Z.0^:rVp~  
    Ol@ YSkd  
    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: QPa&kl  
    enableservice('AutomationServer', true) 7" cgj#  
    enableservice('AutomationServer') <<![3&p#  
    <tTn$<b  
    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 KH&xu,I  
    , v6[#NU_Z  
    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: PFIL)D |G  
    1. 在FRED脚本编辑界面找到参考. `Uw^,r  
    2. 找到Matlab Automation Server Type Library Icf@uQ6  
    3. 将名字改为MLAPP G#0 4h{  
    Xl%&hM  
    tL4xHa6v]  
    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。 WYE[H9x1?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: V9m1n=r  
    1. 创建Matlab服务器。 ^\\cGJ&8c  
    2. 移动探测面对于前一聚焦面的位置。 >b/0i$8  
    3. 在探测面追迹光线 FyQ^@@  
    4. 在探测面计算照度 .,x08M  
    5. 使用PutWorkspaceData发送照度数据到Matlab nyPA`)5F0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 b_=k"d  
    7. 用Matlab画出照度数据 Z;i^h,j?$1  
    8. 在Matlab计算照度平均值 ;xa]ke3]  
    9. 返回数据到FRED中 ^f1}:g
