    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。 4u;9J*r4  
    fV>CZ^=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: xw5d|20b  
    enableservice('AutomationServer', true) !^oV #  
    enableservice('AutomationServer') 2}6%qgnT-  
    2B0W~x2=  
    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 dUrElXbXd

    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: BR`ygrfe  
    1. 在FRED脚本编辑界面找到参考. xM>W2  
    2. 找到Matlab Automation Server Type Library o G*5f  
    3. 将名字改为MLAPP :ue:QSt(u  
    {$D,?V@%_  
    /*FH:T<V  
    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。 0oZsb\

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4S"\~><  
    1. 创建Matlab服务器。 z;f2*F  
    2. 移动探测面对于前一聚焦面的位置。 |~`as(@Ih  
    3. 在探测面追迹光线 .T<= z  
    4. 在探测面计算照度 "Mw[P [w*  
    5. 使用PutWorkspaceData发送照度数据到Matlab Z%zj";C G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Qf M zF  
    7. 用Matlab画出照度数据 !l?.5Pm])  
    8. 在Matlab计算照度平均值 C&LBr|
