    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。  *_ {l  
    0?6 If+AC  
    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: y= oVUsG  
    enableservice('AutomationServer', true) Gdf1+mi  
    enableservice('AutomationServer') 0V>ESyae5  
    s#+"5&!s  
    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 '!+ P{  
    da9*9yN  
    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: HeT6Dv  
    1. 在FRED脚本编辑界面找到参考. z@Z_] h  
    2. 找到Matlab Automation Server Type Library #7-kL7 MK]  
    3. 将名字改为MLAPP <uBhi4

    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。 Mz/]DJ8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: F=-uDtQ <N  
    1. 创建Matlab服务器。 {z5V{M(|w3  
    2. 移动探测面对于前一聚焦面的位置。 8 l'bRyuS  
    3. 在探测面追迹光线 ;gxN@%}@  
    4. 在探测面计算照度 !"`@sd~  
    5. 使用PutWorkspaceData发送照度数据到Matlab ih+*T1#:(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 x9x#'H3  
    7. 用Matlab画出照度数据 [)Z 'N/;0  
    8. 在Matlab计算照度平均值 Qq,i  
    9. 返回数据到FRED中 6?3/Ul }
