    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。 (&x\,19U$  
    zq>"a&Y,  
    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: v" TH[}C9D  
    enableservice('AutomationServer', true) xH-k~#  
        enableservice('AutomationServer') 6>7LFV1tvy  
    K4L#%KUPW  
    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 R.$Y1=U6  
    e%7P$.  
    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: Q#bo!]H{t  
    1. 在FRED脚本编辑界面找到参考. ~OfKn1D  
    2. 找到Matlab Automation Server Type Library / UBAQ8TR  
        3. 将名字改为MLAPP SvJ8Kl OV  
         j`hbQp\`  
         dL"i\5#%A  
    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。 K`2DhJC

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 780MSFV8  
    1. 创建Matlab服务器。 Li$k<AM  
    2. 移动探测面对于前一聚焦面的位置。 ?%n9g)>Yej  
    3. 在探测面追迹光线 r{;4(3E2  
    4. 在探测面计算照度 skArocs  
    5. 使用PutWorkspaceData发送照度数据到Matlab [$+61n}.12  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 zOp"n\  
    7. 用Matlab画出照度数据 N=x,96CF  
    8. 在Matlab计算照度平均值 K",]_+b  
    9. 返回数据到FRED中 @isqFKjph
