    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。 1SQ3-WU s  
    ;Zcswt8]u  
    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: H `XUJh  
    enableservice('AutomationServer', true) >jDDQ@  
    enableservice('AutomationServer') ch*8B(:  
    kP=eW_0D  
    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 P1. [

    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: B-RjMxX4>  
    1. 在FRED脚本编辑界面找到参考. %Bj\W'V&p  
    2. 找到Matlab Automation Server Type Library u74[>^  
    3. 将名字改为MLAPP Q^P}\wb>

    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。 v4!VrI

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  C#.->\  
    1. 创建Matlab服务器。 ~p6 V,Q  
    2. 移动探测面对于前一聚焦面的位置。 %_H<:uGO%  
    3. 在探测面追迹光线 F@D`N0Pte  
    4. 在探测面计算照度 +zqn<<9  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~f2z]JLr:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 V5@:#BIs  
    7. 用Matlab画出照度数据 ZuzEg*lb  
    8. 在Matlab计算照度平均值 RXMISt3+{y  
    9. 返回数据到FRED中 Gm&Za,4%4
