    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。 4 bw8^  
    g:7S/L0]  
    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: oYG9i=lZ  
    enableservice('AutomationServer', true) @2nar<  
    enableservice('AutomationServer') 1k EXTs=,  
    4$oNh)+/h  
    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 +mIO*UQi

    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: bH%k)  
    1. 在FRED脚本编辑界面找到参考. j'R{llZW  
    2. 找到Matlab Automation Server Type Library 2v\,sHw+-  
    3. 将名字改为MLAPP -~n^?0

    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。 G>& Tap>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: z~\a]MB  
    1. 创建Matlab服务器。  >\6Tm  
    2. 移动探测面对于前一聚焦面的位置。 ~)xg7\k  
    3. 在探测面追迹光线 [#hpWNez(>  
    4. 在探测面计算照度 ux`)jOQ`Y]  
    5. 使用PutWorkspaceData发送照度数据到Matlab ce7$r*@!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 A/ZZ[B-  
    7. 用Matlab画出照度数据 R9@Dd  
    8. 在Matlab计算照度平均值 C,r[H5G#  
    9. 返回数据到FRED中 7)SG#|v[$
