    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。 SJ+-H83x  
    A|Gqjy^;@  
    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: GFkte  
    enableservice('AutomationServer', true) ' qS!n  
        enableservice('AutomationServer') Utp\}0GZY  
    S`@*zQ  
    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 Vs"Q-?  
    wVtBeZa  
    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: q0Pu6"^  
    1. 在FRED脚本编辑界面找到参考. R)Fl@ Tn  
    2. 找到Matlab Automation Server Type Library &r!>2$B\  
        3. 将名字改为MLAPP ?7a[| -  
         W<7Bq_L[|  
         [_1G\z_iE  
    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。 dL)5~V8s

    现在将脚本代码公布如下,此脚本执行如下几个步骤: uB5o Ghu-  
    1. 创建Matlab服务器。 1bs95Fh9Q  
    2. 移动探测面对于前一聚焦面的位置。 <sOB j'  
    3. 在探测面追迹光线 CFxs`C^  
    4. 在探测面计算照度 dUSuhT  
    5. 使用PutWorkspaceData发送照度数据到Matlab }cmL{S  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 >z$|O>j  
    7. 用Matlab画出照度数据 S3cQC`^  
    8. 在Matlab计算照度平均值 YO+d+5  
    9. 返回数据到FRED中 ,#Y".23G
