    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。 z1)$  
    @DUN;L 4  
    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: fB@K'JQG  
    enableservice('AutomationServer', true) -(|7`U  
    enableservice('AutomationServer') )jp{*?^\  
    n+:m _2T  
    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 6eW1<p

    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: gizmJ:<  
    1. 在FRED脚本编辑界面找到参考. `S uS)RhA)  
    2. 找到Matlab Automation Server Type Library  rytGr9S  
    3. 将名字改为MLAPP %D`^

    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。 :%+^}

    1. 创建Matlab服务器。 tRpL0 =y  
    2. 移动探测面对于前一聚焦面的位置。 - I1cAt  
    3. 在探测面追迹光线 a 5~G  
    4. 在探测面计算照度 d;*OO xQV  
    5. 使用PutWorkspaceData发送照度数据到Matlab '2Mjz6mBDA  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8ItCfbqa6  
    7. 用Matlab画出照度数据 wC4AVJJ^>  
    8. 在Matlab计算照度平均值 GF$rPY[
