    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。 mOwgk7s[ J  
    Qo  
    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: RBx`<iBe  
    enableservice('AutomationServer', true) Ff>Y<7CQ v  
    enableservice('AutomationServer') Gb 61X6  
    VL5kjF3/  
    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 )ufHk  
    $gDp-7  
    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: L1BpkB  
    1. 在FRED脚本编辑界面找到参考. Lhl) pP17  
    2. 找到Matlab Automation Server Type Library j5z, l  
    3. 将名字改为MLAPP IcL3.(!]l  
    Td[w<m+p<P

    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。 hgj#VY$B

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ,-  ]2s_  
    1. 创建Matlab服务器。 "W6 nW  
    2. 移动探测面对于前一聚焦面的位置。 !N$4.slr<p  
    3. 在探测面追迹光线 xy mK|  
    4. 在探测面计算照度 B2d$!Any  
    5. 使用PutWorkspaceData发送照度数据到Matlab w GZ(bKyO  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w :FH2*  
    7. 用Matlab画出照度数据 w%S<N  
    8. 在Matlab计算照度平均值 NOyLZa'  
    9. 返回数据到FRED中 ?3SlvKI}H`
