    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。 DGrk}   
    2T&n6t$p  
    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: zg+6< .Sf  
    enableservice('AutomationServer', true) ~[ZRE @  
    enableservice('AutomationServer') -?}Z0e(w  
    glI4Jb_[  
    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 1n-+IR"  
    !U[/P6 +0  
    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: jBLLx{  
    1. 在FRED脚本编辑界面找到参考. !L?diR  
    2. 找到Matlab Automation Server Type Library jn,_Ncd#  
    3. 将名字改为MLAPP W^"C|4G}

    AdGDs+at,  
    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。 l)K8.(2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: `E:&a]ul  
    1. 创建Matlab服务器。 J *nWCL  
    2. 移动探测面对于前一聚焦面的位置。 JZ>E<U9&  
    3. 在探测面追迹光线 RTQtXv6mD  
    4. 在探测面计算照度 E=$li  
    5. 使用PutWorkspaceData发送照度数据到Matlab DU|>zO%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 hRaX!QcG3  
    7. 用Matlab画出照度数据 4qvE2W}&  
    8. 在Matlab计算照度平均值 'MK"*W8QRM  
    9. 返回数据到FRED中 -POsbb>
