    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。 >+9f{FP 9  
    |#87|XIJ&~  
    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: A6D@#(D  
    enableservice('AutomationServer', true) myR}~Cj;q  
    enableservice('AutomationServer') 8 2EH'C  
    H{XD>q.  
    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'dW  
    `egyk)"aM  
    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: OdZLJt?g  
    1. 在FRED脚本编辑界面找到参考. Po~u-5  
    2. 找到Matlab Automation Server Type Library {J?#KHF'|  
    3. 将名字改为MLAPP q=_&izmE'7  
    1L4-hYtCj  
    }'"4q  
    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。 "K!9^!4&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |t1ij'N  
    1. 创建Matlab服务器。 _olhCLIR-  
    2. 移动探测面对于前一聚焦面的位置。 Ot^<:\< `G  
    3. 在探测面追迹光线 4X()D {uR  
    4. 在探测面计算照度 "EE=j$8u+  
    5. 使用PutWorkspaceData发送照度数据到Matlab uTX0lu;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |?kZfr&9q  
    7. 用Matlab画出照度数据 tH}$j  
    8. 在Matlab计算照度平均值 ';CL;A;  
    9. 返回数据到FRED中 ~&UfnO
