    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。 %n9aaoD  
    hkQ"OsU  
    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: &^Q/,H~S  
    enableservice('AutomationServer', true) $1`2 kM5  
        enableservice('AutomationServer') z-)O9PV  
    SO0PF|{\r  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 g]0_5?i  
    o&$A]ph8X  
    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: }-=|^  
    1. 在FRED脚本编辑界面找到参考. YNi.SXH  
    2. 找到Matlab Automation Server Type Library 2[02,FG  
        3. 将名字改为MLAPP 9'bwWBf7  
         +52{-a,>  
         0n{=%Q  
    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。 P/_['7

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {R `[kt  
    1. 创建Matlab服务器。 Z4ImV~m  
    2. 移动探测面对于前一聚焦面的位置。 [/8%3  
    3. 在探测面追迹光线 CzrC%xy  
    4. 在探测面计算照度 qUb&   
    5. 使用PutWorkspaceData发送照度数据到Matlab 'TB2:W3  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 R (n2A$  
    7. 用Matlab画出照度数据 hp|YE'uYT  
    8. 在Matlab计算照度平均值 `VguQl_,gA  
    9. 返回数据到FRED中 *\F~[
