    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。 n9wj[t1/  
    5Bzuj`  
    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: U8U/?zW/&  
    enableservice('AutomationServer', true) $o{F  
    enableservice('AutomationServer') VQ/ <09e  
    WJBW:2=;  
    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 zww?

    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: ~ rQ4n9G  
    1. 在FRED脚本编辑界面找到参考. i:AjWC@]  
    2. 找到Matlab Automation Server Type Library nqUH6(  
    3. 将名字改为MLAPP 'aLPTVM^  
    e=YO.HT  
    a  [0N,t  
    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。 H@Kl

    现在将脚本代码公布如下,此脚本执行如下几个步骤: VuP#b'g=|]  
    1. 创建Matlab服务器。 3T Yo  
    2. 移动探测面对于前一聚焦面的位置。 =kyJaT^5[  
    3. 在探测面追迹光线 LS*{]@8q  
    4. 在探测面计算照度 $#g#[ /  
    5. 使用PutWorkspaceData发送照度数据到Matlab zlC^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 iW1$!l>v  
    7. 用Matlab画出照度数据 Z^jGT+ 2
