    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。 `%WU8Yv  
    |*tp16+6  
    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: fXQNHZ|4  
    enableservice('AutomationServer', true) nwCrZW  
    enableservice('AutomationServer') sZF6h=67D  
    3=]sLn0L  
    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 W X6&oy>  
    /%A*aGyIc  
    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: UN<]N76!  
    1. 在FRED脚本编辑界面找到参考. 'F#KM1s  
    2. 找到Matlab Automation Server Type Library $l&(%\pp  
    3. 将名字改为MLAPP 2x0<&Xy#P  
    XAL1|] S  
    -4_$ln w$  
    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。 aPbE;" f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: yd`mG{Z  
    1. 创建Matlab服务器。 V[vl!XM  
    2. 移动探测面对于前一聚焦面的位置。 K~uq,~  
    3. 在探测面追迹光线 J!U}iD@occ  
    4. 在探测面计算照度 '}bgLv  
    5. 使用PutWorkspaceData发送照度数据到Matlab :1KpGj*F  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 AX/m25x  
    7. 用Matlab画出照度数据 :${HQd+  
    8. 在Matlab计算照度平均值 :'*~uJrR  
    9. 返回数据到FRED中 \7'{g@C(
