    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。 5\RKT)%X  
    g:O~1jq  
    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: 9`QWqu[  
    enableservice('AutomationServer', true) A)s  
    enableservice('AutomationServer') YD7i6A  
    i wQ'=M  
    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 U!^\DocAY

    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: :!'aP\uE  
    1. 在FRED脚本编辑界面找到参考. r9z/hm}E  
    2. 找到Matlab Automation Server Type Library |OhNQoTY  
    3. 将名字改为MLAPP r4A%`sk@  
    4Poi:0oOys  
    4E&URl0Bh  
    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。 \oLRNr[F

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =H3 JRRS  
    1. 创建Matlab服务器。 F=$2Gz 'RT  
    2. 移动探测面对于前一聚焦面的位置。 P ;PS+S9  
    3. 在探测面追迹光线 b.Z K1  
    4. 在探测面计算照度 thl{IU  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2< w/GX.  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !7P 1%/  
    7. 用Matlab画出照度数据 ]aXCi"fMs  
    8. 在Matlab计算照度平均值 U}_l]gNn  
    9. 返回数据到FRED中 c+ Ejah+
