    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。 lWW+5  
    {9L5Q  
    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: *myG"@P4hW  
    enableservice('AutomationServer', true) nSS>\$  
    enableservice('AutomationServer') WvujcmOf  
    }^9]jSq5  
    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 7KU~(?|:h

    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: O`WIkBV!  
    1. 在FRED脚本编辑界面找到参考. blGf!4H  
    2. 找到Matlab Automation Server Type Library zF8'i=b&  
    3. 将名字改为MLAPP qz9tr  
    u_PuqRcs  
    x[QZ@rGIW  
    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。 s2FngAM;f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @9Q2$  
    1. 创建Matlab服务器。 Cp#)wxi6[y  
    2. 移动探测面对于前一聚焦面的位置。 R[LsE^  
    3. 在探测面追迹光线 ZU^I H9  
    4. 在探测面计算照度 FW8-'~  
    5. 使用PutWorkspaceData发送照度数据到Matlab Bn?:w\%Ue  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 m 41t(i  
    7. 用Matlab画出照度数据 V >Hf9sZ  
    8. 在Matlab计算照度平均值 NBjeH tT  
    9. 返回数据到FRED中 AVG>_$<
