    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。 xt|^~~ /  
    3CD#OCz7&  
    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: @)d_zWE  
    enableservice('AutomationServer', true) x$q}lJv_  
    enableservice('AutomationServer') k9%o{Uzy  
    1 ^|#QMT  
    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 sSU|N;"Y  
    :\[l~S  
    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""ZFh04  
    1. 在FRED脚本编辑界面找到参考. VpJKH\)Rt(  
    2. 找到Matlab Automation Server Type Library pg%(6dqK4  
    3. 将名字改为MLAPP x=cucZ

    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。 Qs\a&Q=0H

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Z3JUYEAS  
    1. 创建Matlab服务器。 hEHd$tH06  
    2. 移动探测面对于前一聚焦面的位置。 p q`uB  
    3. 在探测面追迹光线 eN<L)a:J_  
    4. 在探测面计算照度 X$5  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2PAu>}W*  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *k7BE_&*0Z  
    7. 用Matlab画出照度数据 X&WP.n)  
    8. 在Matlab计算照度平均值 bkd`7(r  
    9. 返回数据到FRED中 :^ywc O
