    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。 [wHGt?R  
    Aj9<4N  
    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: /_yJ;l/K  
    enableservice('AutomationServer', true) vumA W*  
    enableservice('AutomationServer') $9LI v  
    3[*E>:)qh  
    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 ;onhc*{lv  
    C t-^-XD  
    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: PNNY_t +I  
    1. 在FRED脚本编辑界面找到参考. jIpc^iu`,  
    2. 找到Matlab Automation Server Type Library Yz6+ x]  
    3. 将名字改为MLAPP g9N_s,3jC

    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。 }:6$5/?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: V 4~`yT?*"  
    1. 创建Matlab服务器。 =t,}I\_^c  
    2. 移动探测面对于前一聚焦面的位置。 ?4G/f<ou  
    3. 在探测面追迹光线 S5a?KU  
    4. 在探测面计算照度 ((Jiv=%  
    5. 使用PutWorkspaceData发送照度数据到Matlab $F^p5EXkc6  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~hx__^]d  
    7. 用Matlab画出照度数据 ak_&\'P  
    8. 在Matlab计算照度平均值 aJAQ G  
    9. 返回数据到FRED中 ()Cw;N{E
