    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。 P/;d|M(  
    +ht{ARX2(  
    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: P8=!/L2?  
    enableservice('AutomationServer', true) V Mb r@9  
    enableservice('AutomationServer') OjRJyhzS*  
    WC *e#QP  
    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 +ew9%={zB  
    ;8J+Q0V  
    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: xIb^x=|h  
    1. 在FRED脚本编辑界面找到参考. f_qW+fN::s  
    2. 找到Matlab Automation Server Type Library QGM@m:O  
    3. 将名字改为MLAPP )[d>?%vfd

    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。 WZ]f \S

    现在将脚本代码公布如下,此脚本执行如下几个步骤: w] =q>p  
    1. 创建Matlab服务器。 }Rx`uRx\  
    2. 移动探测面对于前一聚焦面的位置。 8O_0x)X  
    3. 在探测面追迹光线 6x8P}?  
    4. 在探测面计算照度 M9scZuj  
    5. 使用PutWorkspaceData发送照度数据到Matlab !=yNj6_f  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mpysnKH  
    7. 用Matlab画出照度数据 TqN4OkCm/  
    8. 在Matlab计算照度平均值 ()+PP}:$A  
    9. 返回数据到FRED中 \n`)>-
