    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。 $$Tf1hIg  
    x [vb i  
    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: kXdXyq  
    enableservice('AutomationServer', true) o5Rv xGN  
        enableservice('AutomationServer') 43g1/,klm  
    I] +OYWp  
    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 l ?b*T#uIk  
    ?*UWg[  
    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: qOmL\'8  
    1. 在FRED脚本编辑界面找到参考. w^cQL%  
    2. 找到Matlab Automation Server Type Library c0l?+:0M  
        3. 将名字改为MLAPP oNYFbZw  
         6i+AJCkC

    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_H2[d&/>D

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pm9sI4S  
    1. 创建Matlab服务器。 G,+3(C  
    2. 移动探测面对于前一聚焦面的位置。 ~233{vh$=>  
    3. 在探测面追迹光线 1}Guhayy  
    4. 在探测面计算照度 :3s^, g  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5{!"}  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 C \5yo  
    7. 用Matlab画出照度数据 $mf O:%  
    8. 在Matlab计算照度平均值 B^]Gv7-  
    9. 返回数据到FRED中 74NL)|M
