    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。 @d8&3@{R^  
    @m !9"QhC  
    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: DTX/3EN  
    enableservice('AutomationServer', true) rCnV5Yb0O  
    enableservice('AutomationServer') B|Rpm^ |  
     [%gK^Zt  
    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 g]EQ2g_N1  
    UUdu;3E=5  
    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: T U"K#V&u  
    1. 在FRED脚本编辑界面找到参考. Pj1K  
    2. 找到Matlab Automation Server Type Library ,H#qgnp  
    3. 将名字改为MLAPP $S($97IU=  
    G#9o?  
    N \CEocU  
    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。 #z-iL!?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c Eh0Vh-]  
    1. 创建Matlab服务器。 {WM&  
    2. 移动探测面对于前一聚焦面的位置。 MA/"UV&M(  
    3. 在探测面追迹光线 7Ap~7)z[  
    4. 在探测面计算照度 hy!'Q>[`  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5'{qEZs^QU  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1?e>x91  
    7. 用Matlab画出照度数据 >[E|p6jgT
