    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。 BUwL?  
    9i 9 ,X^=  
    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: \>*.+?97  
    enableservice('AutomationServer', true) LH}9&FfjU  
    enableservice('AutomationServer') _vb'3~'S  
    ts(u7CJd  
    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 bBc<p{  
    *w. ":\P]  
    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: t zd#9 #  
    1. 在FRED脚本编辑界面找到参考. R+ \%  
    2. 找到Matlab Automation Server Type Library ^HR8.9^[1u  
    3. 将名字改为MLAPP b{-"GqMO  
    ( ./MFf  
    -1B.A  
    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。 AfhJ6cSIE

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fsK=]~<g  
    1. 创建Matlab服务器。 @=AQr4&  
    2. 移动探测面对于前一聚焦面的位置。 LKI\(%ba#  
    3. 在探测面追迹光线 n6,YA2yZO  
    4. 在探测面计算照度 @,= pG  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]!!?gnPd5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [O^/"Qk  
    7. 用Matlab画出照度数据 Q5dqn"?  
    8. 在Matlab计算照度平均值 FXY>o>K%h  
    9. 返回数据到FRED中 V;RgO}
