    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。 mpIR: Im  
    *Kq;xM6Ck  
    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: L1@<7?@X  
    enableservice('AutomationServer', true) G/(tgQ  
        enableservice('AutomationServer') iM8l,Os]<f  
    @qA11C.hq  
    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 sVnpO$  
    k%N$eO$  
    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: {irl}EeyC  
    1. 在FRED脚本编辑界面找到参考. :2A-;P4  
    2. 找到Matlab Automation Server Type Library LiGECqWBa'  
        3. 将名字改为MLAPP _4k zlD  
         )U}`x }:,  
         }^odUIj  
    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。 9r8bSV3`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: LzEH&y_O  
    1. 创建Matlab服务器。 \x8'K  
    2. 移动探测面对于前一聚焦面的位置。 o6 :]Hvqjr  
    3. 在探测面追迹光线 "p>kiNu  
    4. 在探测面计算照度  Qk.[#  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2,h]Y=.s  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 rZ RTQ  
    7. 用Matlab画出照度数据 >#.du}t  
    8. 在Matlab计算照度平均值 =C^4nP-  
    9. 返回数据到FRED中 h?->A#
