    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。 f]r*;YEc4  
    ;}E}N:A  
    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: D3 C7f'  
    enableservice('AutomationServer', true) )h,y Q`.  
    enableservice('AutomationServer') JN/=x2n.  
    -~]H5er`  
    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 G?}?>O  
    X<,QSTP  
    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: 2p&$bf t  
    1. 在FRED脚本编辑界面找到参考. v^JzbO~|gj  
    2. 找到Matlab Automation Server Type Library I(*3n"  
    3. 将名字改为MLAPP r.e K;

    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。 cANt7

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?+Gt?-! 5q  
    1. 创建Matlab服务器。 xS1|t};  
    2. 移动探测面对于前一聚焦面的位置。 r,JQR)l0@V  
    3. 在探测面追迹光线 Z9DfwWI2nu  
    4. 在探测面计算照度 7*PBJt\  
    5. 使用PutWorkspaceData发送照度数据到Matlab jkL=JAcf~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *<sc[..)  
    7. 用Matlab画出照度数据 $rXCNew(  
    8. 在Matlab计算照度平均值 I#2$CSJ  
    9. 返回数据到FRED中 kU/MvoV
