    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。 {axRq'=  
    I@1VX5  
    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: " "CNw-^t  
    enableservice('AutomationServer', true) >/.Ae8I)  
    enableservice('AutomationServer') N`vPt?@  
    _1jeaV9@  
    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 1NAtg*`  
    uK[gI6M  
    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: l HZ4N{n  
    1. 在FRED脚本编辑界面找到参考. o%h[o9i  
    2. 找到Matlab Automation Server Type Library +1eb@b X  
    3. 将名字改为MLAPP Xx^v%[!`+

    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。 "Fxw"I <

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1Nz#,IdQ  
    1. 创建Matlab服务器。 kP&Ekjt@  
    2. 移动探测面对于前一聚焦面的位置。 G%%5lw!y'  
    3. 在探测面追迹光线 '~xjaa;.  
    4. 在探测面计算照度 O5JG!bGE_F  
    5. 使用PutWorkspaceData发送照度数据到Matlab |W SvAM3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Emv9l~mIu  
    7. 用Matlab画出照度数据 WwLV^m]  
    8. 在Matlab计算照度平均值 I$f'BAw  
    9. 返回数据到FRED中 ?cD_\~
