    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。 R y47Fze  
    *A<vrkHz  
    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: zWs ("L(#s  
    enableservice('AutomationServer', true) g&E3Wc  
    enableservice('AutomationServer') 2Dc2uU@`r  
    38<Z=#S  
    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 azK7kM~  
    -BV8,1  
    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: 0H9UM*O  
    1. 在FRED脚本编辑界面找到参考. dG8_3T}i  
    2. 找到Matlab Automation Server Type Library r`dQ<U,  
    3. 将名字改为MLAPP k-V3l  
    a:v5(@8  
    2}\/_Y6  
    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。 .}n-N #

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Q9G\T:^ury  
    1. 创建Matlab服务器。 -v@LJCK7I  
    2. 移动探测面对于前一聚焦面的位置。 s(.H"_ a  
    3. 在探测面追迹光线 {s7 3(B"  
    4. 在探测面计算照度 " ""k}M2A  
    5. 使用PutWorkspaceData发送照度数据到Matlab mz>GbImVD~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 o=]\Jy  
    7. 用Matlab画出照度数据 !VDNqW  
    8. 在Matlab计算照度平均值 Be$v%4  
    9. 返回数据到FRED中  `1`Qu!
