    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。 L--(Y+vmf  
    g, %xGQ4+  
    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: *Tt*\ O  
    enableservice('AutomationServer', true) pwvcH3l/r  
    enableservice('AutomationServer') iS"(  
    :z!N_]t  
    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 G#pRBA^

    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: #*<*|AwoW|  
    1. 在FRED脚本编辑界面找到参考. !L#>wlX)  
    2. 找到Matlab Automation Server Type Library UA|A>c  
    3. 将名字改为MLAPP }(r%'(.6

    _IOt(Zb(  
    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。 %;E/{gO

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @KhDQ0v]5  
    1. 创建Matlab服务器。 Eo$7W5h J  
    2. 移动探测面对于前一聚焦面的位置。 hK,e<?N^  
    3. 在探测面追迹光线 b$f@.L  
    4. 在探测面计算照度 9$z|kwU  
    5. 使用PutWorkspaceData发送照度数据到Matlab to1{7q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 dT%$"sj5  
    7. 用Matlab画出照度数据 =Kv*M@  
    8. 在Matlab计算照度平均值 ^0/FZ)V8  
    9. 返回数据到FRED中 0z2A!ap
