    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。 q)o;iR  
    bC"h7$3  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: zt9A-% \R  
    enableservice('AutomationServer', true) ~N}Zr$D  
    enableservice('AutomationServer') v!DK.PZbi  
    t'J 4zV  
    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 rNicg]:\x  
    **z^aH?B2  
    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: ^fsC]9NS  
    1. 在FRED脚本编辑界面找到参考. 6:8Nz   
    2. 找到Matlab Automation Server Type Library DF-PBVfpu  
    3. 将名字改为MLAPP x!W5'DO  
    G9xO>Xp^Al  
    Het>G{  
    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。 6Y6t.j0vN.

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9bRUN<  
    1. 创建Matlab服务器。 v5e*R8/  
    2. 移动探测面对于前一聚焦面的位置。 -R1;(n)  
    3. 在探测面追迹光线 vg3iT }  
    4. 在探测面计算照度 {|OXiRm'  
    5. 使用PutWorkspaceData发送照度数据到Matlab e2G;_:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;XyryCo  
    7. 用Matlab画出照度数据 D-t!{LA  
    8. 在Matlab计算照度平均值 pbqk  
    9. 返回数据到FRED中 A7XA?>~+|
