    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。 `L#`WC@[o  
    5q Y+^jO]o  
    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: } 63Qh}_Y  
    enableservice('AutomationServer', true) Jg:%|g  
    enableservice('AutomationServer') `eXTVi|0"~  
    {6,  l#z  
    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 dnXre*rhz  
    N# ?}r>W3  
    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: zv>3Tc0R  
    1. 在FRED脚本编辑界面找到参考. (|kcSnF0  
    2. 找到Matlab Automation Server Type Library |2'u@<(Z/  
    3. 将名字改为MLAPP d=~-8]%\

    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。 L2GUrf

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T|fmO<e*n  
    1. 创建Matlab服务器。 X4z6#S58  
    2. 移动探测面对于前一聚焦面的位置。 !Ic{lB   
    3. 在探测面追迹光线 S]#xG+$<  
    4. 在探测面计算照度 byrK``f  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~8#Ku,vEy  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 F!yr};@^p  
    7. 用Matlab画出照度数据 9+!1jTGSkf  
    8. 在Matlab计算照度平均值 _5%NG 3c  
    9. 返回数据到FRED中 _pZaVx
