    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。 XhUVDmeUMb  
    +GncQs y  
    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: tyFsnc k  
    enableservice('AutomationServer', true) |$g} &P8;  
    enableservice('AutomationServer') f2u4*X E\  
    fp}5QUm-  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 P*n/qj8h  
    hP}-yW6]  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ZCuoYE$g  
    1. 在FRED脚本编辑界面找到参考. qM<CBcON  
    2. 找到Matlab Automation Server Type Library .bUj  
    3. 将名字改为MLAPP 2~R%_r+<  
    '61>.u:2  
    4~1lP&  
    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。 aNBwb9X

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3$S~!fh  
    1. 创建Matlab服务器。 7AlL,&+  
    2. 移动探测面对于前一聚焦面的位置。 :D4'x{#H  
    3. 在探测面追迹光线 Rg^ps  
    4. 在探测面计算照度 1Tr%lO5?6  
    5. 使用PutWorkspaceData发送照度数据到Matlab ICiGZ'k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |{JI=$  
    7. 用Matlab画出照度数据 7'#_uA QR  
    8. 在Matlab计算照度平均值 k136n#KN1  
    9. 返回数据到FRED中 qeb}~FL"o
