    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。 `h+ia/  
    \9*wo9cV  
    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: 7@"J&><w!  
    enableservice('AutomationServer', true) gd3~R+Kd  
    enableservice('AutomationServer') ((L=1]w  
    m/l#hp+  
    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 7kapa59  
    EJ&[I%jU  
    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: jeM %XI  
    1. 在FRED脚本编辑界面找到参考.  J5 PXmL  
    2. 找到Matlab Automation Server Type Library 3D>syf  
    3. 将名字改为MLAPP a!YpSFr  
    _hlLM,p  
    tpp. 9  
    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。 I_xvg >i

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?:F#WDD  
    1. 创建Matlab服务器。 MzLnD D^  
    2. 移动探测面对于前一聚焦面的位置。 u'}SaX]0  
    3. 在探测面追迹光线 #`R`!4  
    4. 在探测面计算照度 / *=1hF  
    5. 使用PutWorkspaceData发送照度数据到Matlab IfF@$eO  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 0 =#)-n  
    7. 用Matlab画出照度数据 L h"K"Uv  
    8. 在Matlab计算照度平均值 R5=2EwrGP  
    9. 返回数据到FRED中 WO{V,<;
