    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。 h/PWi<R i  
    /I: d<A  
    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: ynDa4HB  
    enableservice('AutomationServer', true)  c~dX8+  
    enableservice('AutomationServer') (}bP`[@rX!  
    Rqu;;VI[  
    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 Cm>8r5LG  
    [f^~Z'TIN/  
    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: t?{E_70W  
    1. 在FRED脚本编辑界面找到参考. l6)*u[}E   
    2. 找到Matlab Automation Server Type Library 3\6jzD  
    3. 将名字改为MLAPP fz,8 <

    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。 QNn$`Qz.

    现在将脚本代码公布如下,此脚本执行如下几个步骤: llQDZ}T  
    1. 创建Matlab服务器。 YAd.i@^  
    2. 移动探测面对于前一聚焦面的位置。 [bE9Y;  
    3. 在探测面追迹光线 ;J2=6np  
    4. 在探测面计算照度 yS lN|8d  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5 LXK#+Z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Fy^!*M-  
    7. 用Matlab画出照度数据 BQt!L1))  
    8. 在Matlab计算照度平均值 Kkdd}j  
    9. 返回数据到FRED中 Z#MPlw0B
