    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。 C^ k3*N  
    _ d"Y6 0  
    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: k? _$h<Y  
    enableservice('AutomationServer', true) :O2v0Kx  
    enableservice('AutomationServer') xdSj+507  
    <MDFf nj  
    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 A UO0  
    Z{>Y':\?<  
    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: @zpHem dB  
    1. 在FRED脚本编辑界面找到参考. !-Tmu  
    2. 找到Matlab Automation Server Type Library i =+<7]Q  
    3. 将名字改为MLAPP -1Ki7|0,  
    .cn w?EI  
    ;R-Q,aCM}  
    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。 '"NdT7*+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: tLGwF3e$A  
    1. 创建Matlab服务器。 n$VPh/  
    2. 移动探测面对于前一聚焦面的位置。 Nl>b'G96  
    3. 在探测面追迹光线 - &LZle&M  
    4. 在探测面计算照度 2LK*Cv[  
    5. 使用PutWorkspaceData发送照度数据到Matlab {Eb2<;1o{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Sr-^faL  
    7. 用Matlab画出照度数据 >!WBl Sy  
    8. 在Matlab计算照度平均值 \~m%4kzG8J  
    9. 返回数据到FRED中 "B{xC}Tw
