    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。 = .oHnMX2M  
    k\N4@UK  
    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: ,P6=~q3k  
    enableservice('AutomationServer', true) 0oU=RbC  
    enableservice('AutomationServer') ;/LD)$_  
    [vTMS2  
    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 s_eOcm  
    8]< f$3.  
    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: zgKY4R{V  
    1. 在FRED脚本编辑界面找到参考. XM~~y~j  
    2. 找到Matlab Automation Server Type Library &uM^0eM  
    3. 将名字改为MLAPP t`|,6qEG  
    I,O#X)O|i

    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。 G'x .NL

    现在将脚本代码公布如下,此脚本执行如下几个步骤: P<;7j?  
    1. 创建Matlab服务器。 TJy4<rb  
    2. 移动探测面对于前一聚焦面的位置。 K:r\{#9  
    3. 在探测面追迹光线 ~ 3T,&?r  
    4. 在探测面计算照度 {6 .o=EyM{  
    5. 使用PutWorkspaceData发送照度数据到Matlab kzO&24  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ULBg {e?l8  
    7. 用Matlab画出照度数据 A6UO0lyu  
    8. 在Matlab计算照度平均值 RuAlB*  
    9. 返回数据到FRED中 .ve *Vp
