    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。 8Pva]Q  
    >jnx2$  
    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: VCT1GsnE  
    enableservice('AutomationServer', true) e.Jaq^Gw|  
    enableservice('AutomationServer') .yHK  
    7\X_%SM%  
    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 Ft}nG&D

    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: U lCw{:#F  
    1. 在FRED脚本编辑界面找到参考. -=n!k^?lK  
    2. 找到Matlab Automation Server Type Library Rl_1g`84  
    3. 将名字改为MLAPP I]42R;Sc

    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。 R8YU#D (Q

    现在将脚本代码公布如下,此脚本执行如下几个步骤: R?dMM  
    1. 创建Matlab服务器。 Y1F%-o  
    2. 移动探测面对于前一聚焦面的位置。 - ^Y\'y2  
    3. 在探测面追迹光线 s=1k9   
    4. 在探测面计算照度 E 0OHl  
    5. 使用PutWorkspaceData发送照度数据到Matlab p^Z|$aZZ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Bsk` e  
    7. 用Matlab画出照度数据 ?;Da%VS3  
    8. 在Matlab计算照度平均值 UMMGT6s,E8  
    9. 返回数据到FRED中 ZTj!ti;5
