    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。 +')f6P;t>=  
    L@75- T  
    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: F-D]TRG/*]  
    enableservice('AutomationServer', true) {U 'd}Q  
    enableservice('AutomationServer') g-`~eG28D5  
    72sD0)?A  
    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 pME{jD  
    e__@GBG  
    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: E_F5(x SA  
    1. 在FRED脚本编辑界面找到参考. < v]3g  
    2. 找到Matlab Automation Server Type Library )&era ` e[  
    3. 将名字改为MLAPP ccCzu6

    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。 Zh5RwQNE~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: BR'I+lQ  
    1. 创建Matlab服务器。 j-CnT)W<  
    2. 移动探测面对于前一聚焦面的位置。 \;VhYvEH  
    3. 在探测面追迹光线 $M_x!f'{>  
    4. 在探测面计算照度 @)kO=E d  
    5. 使用PutWorkspaceData发送照度数据到Matlab K.G$]H  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1Z[/KJ  
    7. 用Matlab画出照度数据  hjO*~  
    8. 在Matlab计算照度平均值 {k4CEt;  
    9. 返回数据到FRED中 rC:?l(8ng3
