    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。 [j5+PV  
    :Ae#+([V  
    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: H v/5)  
    enableservice('AutomationServer', true) Md@x2Ja  
        enableservice('AutomationServer') }BU%<5CQ  
    9  @ <  
    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 B>>_t2IU

    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:  %G\nl  
    1. 在FRED脚本编辑界面找到参考. R:&y@/JY8[  
    2. 找到Matlab Automation Server Type Library fh3uo\`@  
        3. 将名字改为MLAPP JygJ4RI%j  
         \wsVO"/  
         5I1YB+$}e  
    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。 } % Ie

    1. 创建Matlab服务器。 E;s_=j1f  
    2. 移动探测面对于前一聚焦面的位置。 J^yqu{

    4. 在探测面计算照度 {[tmz;C  
    5. 使用PutWorkspaceData发送照度数据到Matlab X>yDj]*4P  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ukEJD3i  
    7. 用Matlab画出照度数据 SyI~iW#Y1
