    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。 6J3:[7k=&  
    k.b->U  
    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: P9j[ NEV  
    enableservice('AutomationServer', true) 0'ha!4h3Z  
    enableservice('AutomationServer') R~nbJx$  
    eq)8V x0  
    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+<|fb,a  
    $6~ J#;  
    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:  XI+m  
    1. 在FRED脚本编辑界面找到参考. te e  
    2. 找到Matlab Automation Server Type Library ,r<!30~f  
    3. 将名字改为MLAPP KrwG><+j

    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。 >cm*_26;I

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h`X>b/V  
    1. 创建Matlab服务器。 &6*X&]V!Z  
    2. 移动探测面对于前一聚焦面的位置。 x[]}Jf{t  
    3. 在探测面追迹光线 c#l W ?  
    4. 在探测面计算照度 +k=BD s  
    5. 使用PutWorkspaceData发送照度数据到Matlab i}C9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @I{v  
    7. 用Matlab画出照度数据 # fvt:iE  
    8. 在Matlab计算照度平均值 I7!+~uX  
    9. 返回数据到FRED中 Y/\y"a
