    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。 TpmwD{c[\  
    lY~4'8^  
    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:  %ObLWH'  
    enableservice('AutomationServer', true) _<=S_ <$2  
    enableservice('AutomationServer') }Ow>dV?  
    psnTFe  
    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 $e\h}A6

    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: Ubh{!Y  
    1. 在FRED脚本编辑界面找到参考. Q:|l`*.R  
    2. 找到Matlab Automation Server Type Library %FS$zOsgGK  
    3. 将名字改为MLAPP #VB')^d<U  
    Ma'_e=+A  
    V$"ujRp  
    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。 lc2i`MC

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ddfs8\  
    1. 创建Matlab服务器。 masT>vM  
    2. 移动探测面对于前一聚焦面的位置。 ?lbH02P{v  
    3. 在探测面追迹光线 e1>aTu@  
    4. 在探测面计算照度 |\n@3cIK  
    5. 使用PutWorkspaceData发送照度数据到Matlab -6tgsfEr  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Di@GY!  
    7. 用Matlab画出照度数据 1G0fp:\w  
    8. 在Matlab计算照度平均值 cTXri8K_  
    9. 返回数据到FRED中 PzV@umC1#f
