    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。 ti,d&c_7  
    j<e2d7oN  
    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: sV*H`N')S  
    enableservice('AutomationServer', true) NvX[zqNP_R  
    enableservice('AutomationServer') lH~[f  
    G=bCNn<  
    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 ~pky@O#b  
    <(!:$  
    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: YuwI&)l  
    1. 在FRED脚本编辑界面找到参考. %J-GKpo/S  
    2. 找到Matlab Automation Server Type Library o^wqFX(Y  
    3. 将名字改为MLAPP ~)M~EX&pK

    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。 KqP#6^ _

    现在将脚本代码公布如下,此脚本执行如下几个步骤: +aAc9'k   
    1. 创建Matlab服务器。 a$fnh3j[  
    2. 移动探测面对于前一聚焦面的位置。 /BL4<T f  
    3. 在探测面追迹光线 ?Z}&EH  
    4. 在探测面计算照度 (**oRwr%  
    5. 使用PutWorkspaceData发送照度数据到Matlab -$g#I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #[[ en  
    7. 用Matlab画出照度数据 1{.9uw"2S  
    8. 在Matlab计算照度平均值 DVeE1Q  
    9. 返回数据到FRED中 |5]X| v
