    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。 ~qT+sc!t  
    Q$9`QY*6"p  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: *WgP+"h  
    enableservice('AutomationServer', true) .ODtduURe  
    enableservice('AutomationServer') F'#e]/V1  
    M$gy J!Pb  
    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 zj;y`ENj  
    &[KFCn  
    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: Q\:'gx8`  
    1. 在FRED脚本编辑界面找到参考. Ve8`5  
    2. 找到Matlab Automation Server Type Library u;:N 4d=f'  
    3. 将名字改为MLAPP 6C/D&+4  
    LVLh&9  
    :7!/FBd  
    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。 +o/;bm*U<K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: I|O~F e.  
    1. 创建Matlab服务器。 tY :-13F  
    2. 移动探测面对于前一聚焦面的位置。 O!]w J  
    3. 在探测面追迹光线 M=N`&m\  
    4. 在探测面计算照度 >8tE`2[i*  
    5. 使用PutWorkspaceData发送照度数据到Matlab Gz@%UIv  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 nhCB ])u8l  
    7. 用Matlab画出照度数据 I"JT3[*s  
    8. 在Matlab计算照度平均值  "rjJ"u 1  
    9. 返回数据到FRED中 z4J-qK~2
