    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。 ]?,47,[<  
    @f0~a  
    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: 84P^7[YX>  
    enableservice('AutomationServer', true) )rD] y2^<  
        enableservice('AutomationServer') / /qTMxn  
    ~\hA-l36  
    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 N s9cx  
    .LafP}%  
    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: tklU zv  
    1. 在FRED脚本编辑界面找到参考. ?mY )m +  
    2. 找到Matlab Automation Server Type Library TQK>w'L  
        3. 将名字改为MLAPP 3y>.1

         +3vK=d_Va  
    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。 Ig1cf9 :

    2. 移动探测面对于前一聚焦面的位置。 ,KkENp_  
    3. 在探测面追迹光线 >8SX,  
    4. 在探测面计算照度 5 d|*E_yu  
    5. 使用PutWorkspaceData发送照度数据到Matlab {a_= 4a  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 mT@UQCG  
    7. 用Matlab画出照度数据 ezlp~z"_k  
    8. 在Matlab计算照度平均值 5<4njo?k  
    9. 返回数据到FRED中 PiI ):B>
