    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。 %RW*gUvc]  
    e/4C` J-  
    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: ^C K!=oO  
    enableservice('AutomationServer', true) Yv1yRoDv  
        enableservice('AutomationServer') pauO_'j_1p  
    W(62.3d~}?  
    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 Csu9u'.V  
    ",~ZO<P  
    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: xZ'C(~t  
    1. 在FRED脚本编辑界面找到参考. B/16EuH#  
    2. 找到Matlab Automation Server Type Library n{W(8K6d@[  
        3. 将名字改为MLAPP =o~mZ/ 7=M

         +184|nJ<2  
    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。 +_X*one

    1. 创建Matlab服务器。 fx>QP?Z  
    2. 移动探测面对于前一聚焦面的位置。 SOPair <r  
    3. 在探测面追迹光线 2(uh7#Q  
    4. 在探测面计算照度 wKJ|;o4;L  
    5. 使用PutWorkspaceData发送照度数据到Matlab eSZ':p  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 XnYX@p  
    7. 用Matlab画出照度数据 (e;/Smol  
    8. 在Matlab计算照度平均值 oHfr glGX  
    9. 返回数据到FRED中 `j3 OFC{7E
