    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。 ?U[6X| 1  
    1 gcWw, /  
    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: mMOgx   
    enableservice('AutomationServer', true) RticGQy&5  
    enableservice('AutomationServer') s$qc &  
    Ba5*]VGG  
    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 /kK!xe  
    )=X g  
    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: wIR"!C>LE  
    1. 在FRED脚本编辑界面找到参考. \`["IkSg7  
    2. 找到Matlab Automation Server Type Library tU2#Z=a  
    3. 将名字改为MLAPP jO5R~O`

    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。 mSYm18

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1 I.P7_/  
    1. 创建Matlab服务器。 E`(=n(Qu  
    2. 移动探测面对于前一聚焦面的位置。 ^b`-zFL7  
    3. 在探测面追迹光线 r-L& ee   
    4. 在探测面计算照度 QdcuV\B}  
    5. 使用PutWorkspaceData发送照度数据到Matlab lF.kAEC  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 kZ)}tA7j  
    7. 用Matlab画出照度数据 ?PTXgIC  
    8. 在Matlab计算照度平均值 /SS~IhUX  
    9. 返回数据到FRED中 xP9h$!
