    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。 u^ T2  
    |y]#-T?)t  
    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: K= 69z  
    enableservice('AutomationServer', true) /ZczfM\  
    enableservice('AutomationServer') Z5+0?X0i  
    /XXW4_>  
    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 MG~^>

    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: kxKBI{L  
    1. 在FRED脚本编辑界面找到参考. !v^D j']  
    2. 找到Matlab Automation Server Type Library @g{=f55  
    3. 将名字改为MLAPP RGiA>Z:W  
    gAE}3//  
    mJT7e  
    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。 p~r +2(J

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0c]Lm?&  
    1. 创建Matlab服务器。 fD!O aK  
    2. 移动探测面对于前一聚焦面的位置。 4Ld0AApncy  
    3. 在探测面追迹光线 F Hv|6zUX  
    4. 在探测面计算照度 _-EHG  
    5. 使用PutWorkspaceData发送照度数据到Matlab lVqvS/_k$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6Up,B=sX0  
    7. 用Matlab画出照度数据 !D1F4v[c=  
    8. 在Matlab计算照度平均值 hX;xbl  
    9. 返回数据到FRED中 4b4nFRnH
