    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。 I6}ine ps  
    gKK*` L~  
    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: bbevy!m  
    enableservice('AutomationServer', true) }$-;P=k  
    enableservice('AutomationServer') {%!.aQ,  
    :p^7XwX%w  
    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 iYE:o{  
    r@;n \  
    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: nRKh|B)  
    1. 在FRED脚本编辑界面找到参考. Y{~[N yE  
    2. 找到Matlab Automation Server Type Library 5"1kfB3v  
    3. 将名字改为MLAPP (dl7+

    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。 `4V_I%lJ&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <4!SQgL  
    1. 创建Matlab服务器。 83io@*D  
    2. 移动探测面对于前一聚焦面的位置。 -z"=d<@  
    3. 在探测面追迹光线 ;E? Z<3{  
    4. 在探测面计算照度 1^<R2x  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~3YN;St-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7;H!F!K]  
    7. 用Matlab画出照度数据 Nrp0z:  
    8. 在Matlab计算照度平均值 RtZK2  
    9. 返回数据到FRED中 ~4HS 2\
