    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。 0*6Q 8`I  
    $rPQ%2eF4  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: %.;;itB  
    enableservice('AutomationServer', true) 8*&YQId~  
        enableservice('AutomationServer') Kr+#)S  
    q<4{&omUJ  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 n39EKH rm%  
    f\H1$q\p\  
    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: DDZnNSo<JQ  
    1. 在FRED脚本编辑界面找到参考. &@'+h* b  
    2. 找到Matlab Automation Server Type Library ,vuC0{C^  
        3. 将名字改为MLAPP UtHloq(r  
         ;dTxQ_:  
         mcxD#+H 3  
    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。 gq~"Z[T

    现在将脚本代码公布如下,此脚本执行如下几个步骤: z<8VJZd  
    1. 创建Matlab服务器。 p Moza8  
    2. 移动探测面对于前一聚焦面的位置。 y8 dOx=c  
    3. 在探测面追迹光线 @QF;m  
    4. 在探测面计算照度 P|TM4i]  
    5. 使用PutWorkspaceData发送照度数据到Matlab X#o;`QM  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 P[jh^!<j  
    7. 用Matlab画出照度数据 T NF  
    8. 在Matlab计算照度平均值 )*aAkM  
    9. 返回数据到FRED中 Wl]XOUZ
