    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。 "%]<Co<S  
    L8R{W0Zr>!  
    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: cip5 -Z@8  
    enableservice('AutomationServer', true) tZ\e:AAi  
    enableservice('AutomationServer') ^m pWQ`R  
    ;\a?xtIy  
    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 lgrD~Y (x  
    XNbeYj  
    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: o rBB5JJ  
    1. 在FRED脚本编辑界面找到参考. :`Kv\w.  
    2. 找到Matlab Automation Server Type Library +;,65j+n   
    3. 将名字改为MLAPP .Nk'yow  
    4Ys\<\~d  
    WAq! _xE  
    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。 }Um,wY[tK

    现在将脚本代码公布如下,此脚本执行如下几个步骤: "{9^SPsp  
    1. 创建Matlab服务器。 >E lK8  
    2. 移动探测面对于前一聚焦面的位置。 Wdk]>w 'L  
    3. 在探测面追迹光线 wCQ.?*7-9Q  
    4. 在探测面计算照度  GY`mF1b  
    5. 使用PutWorkspaceData发送照度数据到Matlab xQUskjv/  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 2P, %}Ms  
    7. 用Matlab画出照度数据 >G9YYt~  
    8. 在Matlab计算照度平均值 &ci;0P#Q  
    9. 返回数据到FRED中 !#y_vz9
