    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。 #fM`}Ij.A  
    SSzIih@u  
    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: 0JujesUw(  
    enableservice('AutomationServer', true) #~=Ry H  
    enableservice('AutomationServer') ti,d&c_7  
    Y8t8!{ytg  
    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 es0hm2HT3  
    kD"{g#c  
    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: $<[79al#  
    1. 在FRED脚本编辑界面找到参考. }c:M^Ff  
    2. 找到Matlab Automation Server Type Library WUTowr  
    3. 将名字改为MLAPP ?+8\.a!

    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。 j B{8u&kz)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: "d}Gp9+$VY  
    1. 创建Matlab服务器。 ]hV*r@d  
    2. 移动探测面对于前一聚焦面的位置。 &uVnZ@o42  
    3. 在探测面追迹光线 ;mi%F3  
    4. 在探测面计算照度 akTk(  
    5. 使用PutWorkspaceData发送照度数据到Matlab M D#jj3y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 F((4U"   
    7. 用Matlab画出照度数据 ;5AcFB  
    8. 在Matlab计算照度平均值 qZZK#,Qb  
    9. 返回数据到FRED中 cm+P]8o%{
