    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。 \f6lT3"VN  
    >\Z lZ  
    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: tP&{ J^G  
    enableservice('AutomationServer', true) A&D2T  
    enableservice('AutomationServer') vM5k4%D  
    b?sA EU;  
    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 ^ b=5 6~[  
    "tqS|ok.  
    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: ?SHc}iaU#  
    1. 在FRED脚本编辑界面找到参考. B 9%yd*SJ  
    2. 找到Matlab Automation Server Type Library pHq{S;R2G  
    3. 将名字改为MLAPP q] 2}UuM|U

    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。 \Sz4Gr0g3Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3(oZZz  
    1. 创建Matlab服务器。 2<`gs(oxXe  
    2. 移动探测面对于前一聚焦面的位置。 l:>qR/|m  
    3. 在探测面追迹光线 D4YT33$tC  
    4. 在探测面计算照度 ' [7C~r{%  
    5. 使用PutWorkspaceData发送照度数据到Matlab iKR8^sj7S  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #n6FQ$l8m  
    7. 用Matlab画出照度数据 O=4c eE mz  
    8. 在Matlab计算照度平均值 eSQzjR*  
    9. 返回数据到FRED中 ogkz(wZ
