    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。 ^v()iF !  
    J~PTVR  
    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: 4c493QOd  
    enableservice('AutomationServer', true) 2b vYF ;<r  
    enableservice('AutomationServer') ~cWLu5  
    #CBo  
    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 476M` gA  
    SV$ASs  
    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: dW] Ej"W  
    1. 在FRED脚本编辑界面找到参考. 9 u6 g  
    2. 找到Matlab Automation Server Type Library C 6:pY-  
    3. 将名字改为MLAPP k;9#4^4(  
    CVn;RF6

    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。 |G5=>W

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }1E_G  
    1. 创建Matlab服务器。 |$i1]Dr6  
    2. 移动探测面对于前一聚焦面的位置。 \n('KVbf  
    3. 在探测面追迹光线 ln_EL?V  
    4. 在探测面计算照度 ./z"P]$  
    5. 使用PutWorkspaceData发送照度数据到Matlab FZLzu  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *AJezhR  
    7. 用Matlab画出照度数据 3n=cw2FG  
    8. 在Matlab计算照度平均值 ^!{ oAzy9  
    9. 返回数据到FRED中 QyBK*uNdV
