    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。 QWQJSz5  
    x>!bvZ2  
    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: +Y! P VMF  
    enableservice('AutomationServer', true) Cm"7f !(#  
    enableservice('AutomationServer') )q|a Sd  
    'c/S$_r  
    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 pNnZ-R|u  
    5._1G| 3  
    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: J`[v u4  
    1. 在FRED脚本编辑界面找到参考. FQh8(^(  
    2. 找到Matlab Automation Server Type Library f`vu+nw  
    3. 将名字改为MLAPP n@te.,?A"

    %y|L'C,ge"  
    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。 j;yKL-ycB

    现在将脚本代码公布如下,此脚本执行如下几个步骤: = 9!|%j  
    1. 创建Matlab服务器。 or qL0i  
    2. 移动探测面对于前一聚焦面的位置。 XVfw0-O  
    3. 在探测面追迹光线  P y!$r  
    4. 在探测面计算照度 *8Kx y@  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7R7e3p,K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?#~km0~F)  
    7. 用Matlab画出照度数据 up!54}qy  
    8. 在Matlab计算照度平均值 -T=sY/O  
    9. 返回数据到FRED中 OPuty/^!Gw
