    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。 Qr`WPTQr"  
    2o0.ttBAqZ  
    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: X~/hv_@  
    enableservice('AutomationServer', true) 2?3D` `  
    enableservice('AutomationServer') ^;J@]&[ ~  
    u{0'" jVJ  
    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 bM]\mo>z<

    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: w7b?ve3-  
    1. 在FRED脚本编辑界面找到参考. t`b>iX%(1t  
    2. 找到Matlab Automation Server Type Library Vp =  
    3. 将名字改为MLAPP <8U qV.&

    :e-&,K  
    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。 eySV -f{

    现在将脚本代码公布如下,此脚本执行如下几个步骤: */gm! :Ym  
    1. 创建Matlab服务器。 S~WsGLF s  
    2. 移动探测面对于前一聚焦面的位置。 Pb0+ z=L  
    3. 在探测面追迹光线 jEQr{X7bEL  
    4. 在探测面计算照度 z/bJDSQ  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9/$D&tRN  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3L24|-GxH  
    7. 用Matlab画出照度数据 (bfHxkR.  
    8. 在Matlab计算照度平均值 ],ow@}  
    9. 返回数据到FRED中 ebk{p <
