    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。 ~ j`; $o  
    )lo;y~ 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: @,Iyn<v{B  
    enableservice('AutomationServer', true) MyyNYZ  
    enableservice('AutomationServer') bH-QF\>  
    #0WGSIht<  
    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 vThK@P!s  
    QD}'2{M!  
    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: : ;nvqbd  
    1. 在FRED脚本编辑界面找到参考. xSQ:#o=8G  
    2. 找到Matlab Automation Server Type Library "0(H! }D  
    3. 将名字改为MLAPP QyGTm"9l

    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。 7( &\)qf=n

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Wy[Ua#Dd  
    1. 创建Matlab服务器。 R3;,EL{H&  
    2. 移动探测面对于前一聚焦面的位置。 ._uXK[c7P  
    3. 在探测面追迹光线 W?n)IBj8  
    4. 在探测面计算照度 '9+JaB  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5ir[}I^z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {*Ag[HS0u  
    7. 用Matlab画出照度数据 e-Xr^@M*Q  
    8. 在Matlab计算照度平均值 Lad8C  
    9. 返回数据到FRED中 xb2xl.2x!
