    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。 abAw#XQ8  
    =9Vo[  
    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: b^STegz  
    enableservice('AutomationServer', true) U(PW$\l  
    enableservice('AutomationServer') nQOzKw<j%  
    !F:mD ZeY  
    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 C B`7KK

    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: !{4'=+  
    1. 在FRED脚本编辑界面找到参考. ^AShy`o^X  
    2. 找到Matlab Automation Server Type Library `g_r<EY8/  
    3. 将名字改为MLAPP m2H?VY .^K

    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。 76o3Sge:

    现在将脚本代码公布如下,此脚本执行如下几个步骤: v8WT?%  
    1. 创建Matlab服务器。 Dpwqg3,  
    2. 移动探测面对于前一聚焦面的位置。 QI'-I\Co  
    3. 在探测面追迹光线 =]5f\f6  
    4. 在探测面计算照度 {+ Ibi{  
    5. 使用PutWorkspaceData发送照度数据到Matlab em95ccs'-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 blWtC/!Aq;  
    7. 用Matlab画出照度数据 ySB0"bl  
    8. 在Matlab计算照度平均值 wMw}3qX$j  
    9. 返回数据到FRED中 @U4hq7xzV2
