    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。 3Z)vJC9'  
    +>h'^/rAE  
    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: ;#D:S6 L  
    enableservice('AutomationServer', true) Vzrp9&loY  
        enableservice('AutomationServer') Se5jxV  
    }WkR-5N  
    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 bF3}L=z  
    DOo34l6#  
    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: gJn_8\,C>Q  
    1. 在FRED脚本编辑界面找到参考. i*vf(0G  
    2. 找到Matlab Automation Server Type Library v/Ei0}e6~  
        3. 将名字改为MLAPP 5@Lz4 `  
         tO QY./I  
         a_(vpD^  
    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。 Jqi^Z*PuX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: PAXdIh[]  
    1. 创建Matlab服务器。 T%:W6fH7  
    2. 移动探测面对于前一聚焦面的位置。 bxg9T(Bj  
    3. 在探测面追迹光线 g*#.yC1/  
    4. 在探测面计算照度 Y_&)>;  
    5. 使用PutWorkspaceData发送照度数据到Matlab a)8M'f_z  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 #PRkqg+|  
    7. 用Matlab画出照度数据 ?\Jl] {i2  
    8. 在Matlab计算照度平均值 {7X80KI  
    9. 返回数据到FRED中 wg,w;Gle
