    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。 m<j8cJ(  
    ]%?YZn<{  
    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: P!+'1KR  
    enableservice('AutomationServer', true) .y@oz7T5  
    enableservice('AutomationServer') `bZ/haU}A  
    p2DrEId  
    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 <8d^^0

    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: Il= W,/y  
    1. 在FRED脚本编辑界面找到参考. j( RWO  
    2. 找到Matlab Automation Server Type Library qoj$]   
    3. 将名字改为MLAPP FRg^c kb"

    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。 v?& -xH-S

    现在将脚本代码公布如下,此脚本执行如下几个步骤: dt`{!lts'  
    1. 创建Matlab服务器。 ^(|vsFzn  
    2. 移动探测面对于前一聚焦面的位置。 2\7`/,U6  
    3. 在探测面追迹光线 .zn;:M#T  
    4. 在探测面计算照度 ]cGA~d  
    5. 使用PutWorkspaceData发送照度数据到Matlab z#]Jv!~EPE  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]8 f ms(  
    7. 用Matlab画出照度数据 5ZMR,SZhC  
    8. 在Matlab计算照度平均值 2ioQb`=  
    9. 返回数据到FRED中 HA2k [F@3^
