    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。 )>V?+L5M  
    gljo;f:  
    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: 1RLym9JN  
    enableservice('AutomationServer', true) V43TO  
    enableservice('AutomationServer') {?Od{d9  
    =_l)gx+Y+y  
    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 lCR!:~

    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: PQ$sOK|/  
    1. 在FRED脚本编辑界面找到参考. ?E6^!4=,  
    2. 找到Matlab Automation Server Type Library cMaOM}mS  
    3. 将名字改为MLAPP 2VA!&`I  
    R:M,tL-l  
    U6<M/>RG$  
    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。 Xd3}Vn=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1yM r~Fo  
    1. 创建Matlab服务器。 4 j X3lq|  
    2. 移动探测面对于前一聚焦面的位置。 2Q@Y^t   
    3. 在探测面追迹光线 :S -";.:"  
    4. 在探测面计算照度 FQk!d$BG  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]n;1x1'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 H>XFz(LWh  
    7. 用Matlab画出照度数据 Qs%B'9")  
    8. 在Matlab计算照度平均值 2}vNSQvG  
    9. 返回数据到FRED中 tlQC6Fb#
