    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。 7_ZfV? .  
    " :@5|4qK  
    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: vRYfB{~  
    enableservice('AutomationServer', true) 0,E*9y}  
    enableservice('AutomationServer') 349W0>eOT  
    bK<'J=#1  
    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 3g^_Fq'

    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: %F]4)XeW-+  
    1. 在FRED脚本编辑界面找到参考. MCjf$pZN]  
    2. 找到Matlab Automation Server Type Library z~UqA1r  
    3. 将名字改为MLAPP m\O<Yc keA  
    dzKI?i)x  
    edx-R-Dc-1  
    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。 CcG{+-= H)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: _ 2R;@[f2  
    1. 创建Matlab服务器。 ~$Xz~#~  
    2. 移动探测面对于前一聚焦面的位置。 Akb#1Ww4  
    3. 在探测面追迹光线 xf_NHKZ)  
    4. 在探测面计算照度 iLIH |P%  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5k)/SAU0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 h2QoBGL5  
    7. 用Matlab画出照度数据 s9>-Q"(y  
    8. 在Matlab计算照度平均值 j(AN] g:  
    9. 返回数据到FRED中 h;u8{t"
