    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。 N6\rjYx+7  
    9+PAyI#w  
    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: V,0$mBYa  
    enableservice('AutomationServer', true) 'SoBB:  
    enableservice('AutomationServer') wy tMoG\  
    s-+-?$K  
    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 C;K+ITlJ

    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: KK2YT/K$SG  
    1. 在FRED脚本编辑界面找到参考. -m=A1~|7  
    2. 找到Matlab Automation Server Type Library W Zm8!Y  
    3. 将名字改为MLAPP KYJP`va6k

    j/=Tj'S?D  
    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。 E;x-O)(&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ".$kOH_:  
    1. 创建Matlab服务器。 gh\u@#$8  
    2. 移动探测面对于前一聚焦面的位置。 TK[[6IB  
    3. 在探测面追迹光线 +y8Y@e}>  
    4. 在探测面计算照度 ;CF:cH*  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1Q!^*D  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xH{-UQ3R  
    7. 用Matlab画出照度数据 -Yh(bS l  
    8. 在Matlab计算照度平均值 uax0%~O\  
    9. 返回数据到FRED中 Z_4%Oi
