    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。 <4O=[Q5S  
    tXp)o >"  
    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: G)e 20Mst  
    enableservice('AutomationServer', true) vW4 f3(/  
    enableservice('AutomationServer') Wc]Fg9E  
    \\/X+4|o'  
    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 gf3/kll9

    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>7  
    1. 在FRED脚本编辑界面找到参考. =Wjm_Rvk9  
    2. 找到Matlab Automation Server Type Library p[/n[@<8=  
    3. 将名字改为MLAPP ' l!QGKz  
    ~z aV.3#  
    I 9u=RI s  
    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。 T4f:0r;^f*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %2L9kw'  
    1. 创建Matlab服务器。 X'u`\<&W  
    2. 移动探测面对于前一聚焦面的位置。 :qT>m  
    3. 在探测面追迹光线 IcIMa  
    4. 在探测面计算照度 PAc~p8S  
    5. 使用PutWorkspaceData发送照度数据到Matlab d@l;dos),  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8ziYav  
    7. 用Matlab画出照度数据 % idnm  
    8. 在Matlab计算照度平均值 1U9iNki  
    9. 返回数据到FRED中 P`oR-D
