    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。 :0'2m@x~  
    Z&[_8Y5j  
    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: hQPNxpe  
    enableservice('AutomationServer', true) W&HF*Aw  
    enableservice('AutomationServer') ]46#u=y~3  
    X\ bXat+  
    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 c D0-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: f\]splL  
    1. 在FRED脚本编辑界面找到参考.  HLsG<#  
    2. 找到Matlab Automation Server Type Library W v4o:_}  
    3. 将名字改为MLAPP d&ap u{  
    QxS=W2iN

    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。 GT3 ?)g{Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~4'AnoD1w  
    1. 创建Matlab服务器。 o b,%); m  
    2. 移动探测面对于前一聚焦面的位置。 ?X5Y8n]y\h  
    3. 在探测面追迹光线 M# a1ev  
    4. 在探测面计算照度 \Uh$%#}.  
    5. 使用PutWorkspaceData发送照度数据到Matlab nlsif  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6L4<c+v_  
    7. 用Matlab画出照度数据 *%;+3SV  
    8. 在Matlab计算照度平均值 >jH%n(TcC  
    9. 返回数据到FRED中 K|^'`FpPO
