    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。 RaTH\ >n  
    \cLSf=  
    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: "z<azs  
    enableservice('AutomationServer', true) F} d  
    enableservice('AutomationServer') ]qB:PtX  
    <A9y9|>o  
    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 8?Z4-6!{V,  
    H_?o-L?+  
    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: B>Wu;a.:L  
    1. 在FRED脚本编辑界面找到参考. ?b!Fa  
    2. 找到Matlab Automation Server Type Library *6 U&Qy-M  
    3. 将名字改为MLAPP H\ 1qI7N C

    0R0{t=VJZ  
    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。 2m>-dqg

    现在将脚本代码公布如下,此脚本执行如下几个步骤: bJ_cId8+  
    1. 创建Matlab服务器。 OTZ_c1"K  
    2. 移动探测面对于前一聚焦面的位置。 |;A/|F0-e  
    3. 在探测面追迹光线 >\w&6 i~  
    4. 在探测面计算照度 y&_m 4Zw"  
    5. 使用PutWorkspaceData发送照度数据到Matlab i!~'M;S  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 OUP?p@%]<  
    7. 用Matlab画出照度数据 s s 3t  
    8. 在Matlab计算照度平均值 Qo =Kqv  
    9. 返回数据到FRED中 $W;b{H=F
