    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。 H~&9xtuHN  
    ?^0#:QevC  
    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:  k:R9wo  
    enableservice('AutomationServer', true) (Z sdj  
    enableservice('AutomationServer') 8ec~"vGLz~  
    $O7>E!uVD  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 {P(IA2J'S  
    H<dm;cU  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Ci=c"JdB  
    1. 在FRED脚本编辑界面找到参考. [JsQ/|=z  
    2. 找到Matlab Automation Server Type Library 2i8'*L+j  
    3. 将名字改为MLAPP amgYr$)m  
    6SW:'u|90  
    *T*MLD]Q  
    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。 PJ9JRG7j

    现在将脚本代码公布如下,此脚本执行如下几个步骤: F71.%p7C8"  
    1. 创建Matlab服务器。 .#EmE'IP*  
    2. 移动探测面对于前一聚焦面的位置。 ln#Lx&r;|  
    3. 在探测面追迹光线 !)KX?i[Q  
    4. 在探测面计算照度 M {_`X  
    5. 使用PutWorkspaceData发送照度数据到Matlab : !J!l u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 e>y"V; Mj  
    7. 用Matlab画出照度数据 MX6;ww  
    8. 在Matlab计算照度平均值 >=[w{Vn'Mf  
    9. 返回数据到FRED中 ?ZE1>L7e
