    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。 K@0gBgN  
    _dg2i|yP<  
    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: RA5*QW  
    enableservice('AutomationServer', true)  (C1@f!Z  
    enableservice('AutomationServer') NTj:+z0  
    r$=YhI/=  
    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 Y(:.f-Du  
    O-5s}RT  
    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: -Odk'{nW  
    1. 在FRED脚本编辑界面找到参考. T(n<@Ac]V  
    2. 找到Matlab Automation Server Type Library 9lT6fW`v1Q  
    3. 将名字改为MLAPP ;t^8lC?>V  
    .1O  
    vocXk_  
    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。 yP&SA+

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  xr }jw  
    1. 创建Matlab服务器。 z3 zN^ZT  
    2. 移动探测面对于前一聚焦面的位置。 R^nkcLFb/q  
    3. 在探测面追迹光线 8ec6J*b  
    4. 在探测面计算照度 #fF~6wopV  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^5"2s:vP  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Y<A593  
    7. 用Matlab画出照度数据 <%@S-+D`]  
    8. 在Matlab计算照度平均值 )ifEgBT  
    9. 返回数据到FRED中 /^BaQeH?R
