    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。 &|Cd1z#?  
    ~/m=Q<cV  
    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: h*B7UzCg  
    enableservice('AutomationServer', true) 5e|yW0o  
    enableservice('AutomationServer') W:S?_JM  
    hj+iB,8  
    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 efX iZ

    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: P,W(9&KM  
    1. 在FRED脚本编辑界面找到参考. _/[}PQC6G  
    2. 找到Matlab Automation Server Type Library ^+k~{F,)  
    3. 将名字改为MLAPP `JzP V/6

    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。 :/XWk %

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \ Dccf_(Pb  
    1. 创建Matlab服务器。 cP2n,>:  
    2. 移动探测面对于前一聚焦面的位置。 p:?h)'bA<  
    3. 在探测面追迹光线 ,vs#(d6G  
    4. 在探测面计算照度 GzEvp  
    5. 使用PutWorkspaceData发送照度数据到Matlab _h^er+d!_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 5iZx -M  
    7. 用Matlab画出照度数据 cTa$t :K@  
    8. 在Matlab计算照度平均值 Lu5lpeSQ  
    9. 返回数据到FRED中 34c+70x7
