    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。 ,=CipL9]  
    =7TWzUCO#  
    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: ~SBW`=aP}  
    enableservice('AutomationServer', true) l-W)? d  
        enableservice('AutomationServer') ZiY2N*,VO  
    XGR63hXND  
    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 D3aX\ NGP

    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: [dLc+h1{B  
    1. 在FRED脚本编辑界面找到参考. G3|23G.~)(  
    2. 找到Matlab Automation Server Type Library vcy1itY  
        3. 将名字改为MLAPP KL?<lp"

    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_faqmZ 9]

    现在将脚本代码公布如下,此脚本执行如下几个步骤: VB  |k  
    1. 创建Matlab服务器。 2u_=i$xW  
    2. 移动探测面对于前一聚焦面的位置。 W:n\,P  
    3. 在探测面追迹光线 )x [=}0C  
    4. 在探测面计算照度 l2W+VBn6  
    5. 使用PutWorkspaceData发送照度数据到Matlab VJK4C8]  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 bny@AP(CY+  
    7. 用Matlab画出照度数据 Ke@Bf  
    8. 在Matlab计算照度平均值 JfJ ln[  
    9. 返回数据到FRED中 exSwx-zxI
