    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。 ?0) @jc=  
    61>f(?s  
    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: E-F5y  
    enableservice('AutomationServer', true) MQ9vPgh  
    enableservice('AutomationServer') ]5)"gL%H`  
    `M0YAiG  
    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 v2=/[E@  
    [4\aYB9N  
    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: 6klD22b2$  
    1. 在FRED脚本编辑界面找到参考. ZPvf-Pq Jl  
    2. 找到Matlab Automation Server Type Library yzg9I  
    3. 将名字改为MLAPP p&O8qAaO

    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。 > Y ] _K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: bBG/gQ  
    1. 创建Matlab服务器。 M}KZG'7  
    2. 移动探测面对于前一聚焦面的位置。 1!1DuQ  
    3. 在探测面追迹光线 +`Fb_m)f  
    4. 在探测面计算照度 tvT4S  
    5. 使用PutWorkspaceData发送照度数据到Matlab 4|=vxJ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 b}}y=zO|$  
    7. 用Matlab画出照度数据 y;r"+bS8  
    8. 在Matlab计算照度平均值 8,y{q9O  
    9. 返回数据到FRED中 FR["e1<0
