    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。 1PwtzH .w  
     lrv-[}}  
    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: ^}-l["u`  
    enableservice('AutomationServer', true) _:m70%i  
        enableservice('AutomationServer') .pUB.l$)  
    -pYmM d,  
    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 PF`uwx@zH  
    >+dS PI  
    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: p2gdA J  
    1. 在FRED脚本编辑界面找到参考. _k2R^/9Ct%  
    2. 找到Matlab Automation Server Type Library YP02/*'  
        3. 将名字改为MLAPP jum"T\  
         dA h cA.  
         })-V,\  
    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。 y]jx-w c3O

    现在将脚本代码公布如下,此脚本执行如下几个步骤: SiaNL:  
    1. 创建Matlab服务器。 2X2Ax~d@  
    2. 移动探测面对于前一聚焦面的位置。 %]LoR$|Y  
    3. 在探测面追迹光线 |URfw5Hm  
    4. 在探测面计算照度 M +OVqTsFU  
    5. 使用PutWorkspaceData发送照度数据到Matlab S5hc@^|0Z  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 7T)y"PZ  
    7. 用Matlab画出照度数据 Bo "9;F  
    8. 在Matlab计算照度平均值 {A0F/#M]  
    9. 返回数据到FRED中 #g6_)B=S
