    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。 J?Bj=b  
    r XT6u  
    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: NOSL b];  
    enableservice('AutomationServer', true) bx%Ky0Z  
        enableservice('AutomationServer') 9fy[%M  
    SuA  @S  
    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 S&F[\4w5]

    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: ]T=o>%  
    1. 在FRED脚本编辑界面找到参考. .I Io   
    2. 找到Matlab Automation Server Type Library V'FKgzd  
        3. 将名字改为MLAPP #AH gY.

    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。 Mw`S.M. B

    2. 移动探测面对于前一聚焦面的位置。 CG ,H  
    3. 在探测面追迹光线 rRX F@  
    4. 在探测面计算照度 vt#&YXu{A  
    5. 使用PutWorkspaceData发送照度数据到Matlab qN'%q+n  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 gm$<U9L\v  
    7. 用Matlab画出照度数据 +^q- v-  
    8. 在Matlab计算照度平均值 G;e)K\[J  
    9. 返回数据到FRED中 z(#CO<C.t
