    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。 3 fj  
    \*vHB`.,ey  
    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: x[_=#8~.1x  
    enableservice('AutomationServer', true) "8)z=n  
    enableservice('AutomationServer') I&yVx8aH}  
    ZfAzc6J?\  
    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 JtKp(k&  
    M)-6T{[IT  
    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: /a9 !Cf  
    1. 在FRED脚本编辑界面找到参考. Xf'=+f2p  
    2. 找到Matlab Automation Server Type Library "Y: /= Gx  
    3. 将名字改为MLAPP q6#<[ 4?  
    9' 1B/{  
    \/`?  
    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。 ={2!c0s

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &jA\hg#9  
    1. 创建Matlab服务器。 >c8GW >\N  
    2. 移动探测面对于前一聚焦面的位置。 R{Z-m2La  
    3. 在探测面追迹光线 ,Dmc2D  
    4. 在探测面计算照度 q-$`k  
    5. 使用PutWorkspaceData发送照度数据到Matlab RSfM]w}Hq#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 y8Xv~4qQW  
    7. 用Matlab画出照度数据 5FKBv e@
