    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。 +?o!"SJ  
    %(/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: pS ](Emn`.  
    enableservice('AutomationServer', true) iv *$!\Cd  
    enableservice('AutomationServer') @NRN#~S,_]  
    <7\j\`  
    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 \j`0 f=z_

    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: H dqB B   
    1. 在FRED脚本编辑界面找到参考. {k_\1t(/  
    2. 找到Matlab Automation Server Type Library ?o;ip  
    3. 将名字改为MLAPP [:cD  
    bt)C+|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。 *O~y6|U?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c#{lXS^  
    1. 创建Matlab服务器。 vYm:V:7Y2  
    2. 移动探测面对于前一聚焦面的位置。 IRm}?hHf  
    3. 在探测面追迹光线 :$b` n  
    4. 在探测面计算照度 @c]KHWI  
    5. 使用PutWorkspaceData发送照度数据到Matlab  k;+TN9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 72OqXa*  
    7. 用Matlab画出照度数据 A,<5W }  
    8. 在Matlab计算照度平均值 *HR pbe2  
    9. 返回数据到FRED中 &S{r;N5u
