    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。 xdm\[s  
    NBY|U{.g  
    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: :86:U 0^  
    enableservice('AutomationServer', true) rBNVI;JZW  
    enableservice('AutomationServer') , :#bo]3  
    {9U!0h-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 ;_e9v,  
    5M~{MdF|.  
    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: ;na%*G`  
    1. 在FRED脚本编辑界面找到参考. 3X`9&0:j%  
    2. 找到Matlab Automation Server Type Library o5tCbsHj-  
    3. 将名字改为MLAPP QMsq4yJ)%  
    oT):#,s  
    I[Lg0H8  
    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。 q[a\a7U z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: QDg5B6>$  
    1. 创建Matlab服务器。 P3&s<mh  
    2. 移动探测面对于前一聚焦面的位置。 6M*z`B{hV  
    3. 在探测面追迹光线 FOsd{Fw  
    4. 在探测面计算照度 i D IY|  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1@}F8&EZ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 hpF_@n  
    7. 用Matlab画出照度数据 ~R w1  
    8. 在Matlab计算照度平均值 {Ya$Q#l  
    9. 返回数据到FRED中 AygdAg'\
