    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。 zBp{K@U[|M  
    -}4NT{E  
    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: +|{RE.DL  
    enableservice('AutomationServer', true) Q33"u/-v  
    enableservice('AutomationServer') ,7)C"  
    -:9P%jWt  
    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 h:)Ci!D;  
    zT|)uP*  
    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: #9 fWAF  
    1. 在FRED脚本编辑界面找到参考. X!},8}~J~  
    2. 找到Matlab Automation Server Type Library K+)%KP  
    3. 将名字改为MLAPP ZBG}3Z   
    GF:`>u{C  
    GK}'R=   
    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。 ~!d/8?!

    1. 创建Matlab服务器。 ?Xo*1Z =  
    2. 移动探测面对于前一聚焦面的位置。 %|l8f>3[

    4. 在探测面计算照度 h~,JdDV8l*  
    5. 使用PutWorkspaceData发送照度数据到Matlab g3sUl&K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 oi&Wo'DX  
    7. 用Matlab画出照度数据 Yy JPHw)Z
