    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。 i"2[OM\j7  
    /WXy!W30<  
    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: yHkZInn  
    enableservice('AutomationServer', true) p% ESp&  
    enableservice('AutomationServer') 4&;.>{ :;  
    BFmYbK  
    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 @sv==|h

    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: dP[l$/  
    1. 在FRED脚本编辑界面找到参考. JViglO1\  
    2. 找到Matlab Automation Server Type Library 2)]C'  
    3. 将名字改为MLAPP 6r"uDV #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。 r(NfVQF

    2. 移动探测面对于前一聚焦面的位置。 )iadu  
    3. 在探测面追迹光线 qR0V\OtgY~  
    4. 在探测面计算照度 6#VG,'e3  
    5. 使用PutWorkspaceData发送照度数据到Matlab .b>1u3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %J4]T35^2  
    7. 用Matlab画出照度数据 U*F|Z4{W  
    8. 在Matlab计算照度平均值 9frP`4<)
