    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。 cXG$zwS\  
    |GnqfD  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: b0!ZA/YC-  
    enableservice('AutomationServer', true) 3eJ"7sftW  
    enableservice('AutomationServer') 4WZ"8  
    ?9m@ S#@  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 AWn$od`#s  
    FW--|X]8   
    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: #a=~a=c(^  
    1. 在FRED脚本编辑界面找到参考.  N2Q%/}+,  
    2. 找到Matlab Automation Server Type Library f%5 s8)  
    3. 将名字改为MLAPP ^h\Y.  
    ':LV"c4 t  
     /DN!"  
    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。 x4nmDEpa

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h!h<!xaclW  
    1. 创建Matlab服务器。 m*Q*{M_e  
    2. 移动探测面对于前一聚焦面的位置。 /5 6sPl 7}  
    3. 在探测面追迹光线 %_%/ym  
    4. 在探测面计算照度 76rRF   
    5. 使用PutWorkspaceData发送照度数据到Matlab } qn@8}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 'SE?IE{  
    7. 用Matlab画出照度数据 52>,JHq  
    8. 在Matlab计算照度平均值 25CO_  
    9. 返回数据到FRED中 ej&ZE n
