    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。 3pq&TYQU  
    #nn2odR  
    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: J}<k`af  
    enableservice('AutomationServer', true) [\. ho9  
    enableservice('AutomationServer') Xt9?7J#\T  
    eK3J9 ;X  
    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 '<8ewU

    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: spn1Ji  
    1. 在FRED脚本编辑界面找到参考. :^?ZVi59j  
    2. 找到Matlab Automation Server Type Library iVnrv`k,  
    3. 将名字改为MLAPP c+-L>dsss  
    m"@M~~bh  
    4JP01lq'\  
    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。 xae}8E

    现在将脚本代码公布如下,此脚本执行如下几个步骤: _.wLQL~y  
    1. 创建Matlab服务器。 %,>> <8  
    2. 移动探测面对于前一聚焦面的位置。 '{U56^b]  
    3. 在探测面追迹光线 q4(&.Al\@  
    4. 在探测面计算照度 E%jOJA  
    5. 使用PutWorkspaceData发送照度数据到Matlab vZ$uD,@;.  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 USe"1(|E  
    7. 用Matlab画出照度数据 sDWX} NV  
    8. 在Matlab计算照度平均值 D='/-3f!F]  
    9. 返回数据到FRED中 B 2&fvv?
