    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。 Ze3sc$fG2  
    @WuG8G  
    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: s>a(#6Q  
    enableservice('AutomationServer', true) c#T0n !}  
    enableservice('AutomationServer') S*(n s<L  
    Ta)6ly7'  
    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 wQrD(Dv(yA  
    f=Kt[|%'e  
    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: 43/!pW  
    1. 在FRED脚本编辑界面找到参考. DX<xkS[P  
    2. 找到Matlab Automation Server Type Library S !R:a>\  
    3. 将名字改为MLAPP Rqun}v}

    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。 d^G5Pq

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4 moVS1  
    1. 创建Matlab服务器。 E>NL/[1d  
    2. 移动探测面对于前一聚焦面的位置。 1w|u ^[~u\  
    3. 在探测面追迹光线 `l<pH<F  
    4. 在探测面计算照度 {>zQW{!  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^ZG 3{>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !K/zFYl  
    7. 用Matlab画出照度数据 <'92\O  
    8. 在Matlab计算照度平均值 c7/fQc)h4d  
    9. 返回数据到FRED中 jWerX -$
