    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.IU!.Uo  
    #!)n {h+  
    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: I4&::y^ C  
    enableservice('AutomationServer', true) >3c@x  
    enableservice('AutomationServer') 3E 3HL7  
    ~#kT _*sw)  
    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 e^ v.)

    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: qL,tYJ<m%  
    1. 在FRED脚本编辑界面找到参考. lkBdl#]9  
    2. 找到Matlab Automation Server Type Library EY \H=@A  
    3. 将名字改为MLAPP I_A@BnM{I

    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。 Uh][@35 p

    现在将脚本代码公布如下,此脚本执行如下几个步骤: A]XZnQ  
    1. 创建Matlab服务器。 QcgfBsv96  
    2. 移动探测面对于前一聚焦面的位置。 .w]GWL  
    3. 在探测面追迹光线 < P`u}  
    4. 在探测面计算照度 )KP5Wud X  
    5. 使用PutWorkspaceData发送照度数据到Matlab _)\c&.p]f  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;&ASkI  
    7. 用Matlab画出照度数据 }Q";aU0^  
    8. 在Matlab计算照度平均值 48Mpf=f`  
    9. 返回数据到FRED中 KCWc`Oz
