    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。 o+}>E31a  
    m|/q o  
    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: Exu5|0AAE  
    enableservice('AutomationServer', true) YA?46[:  
    enableservice('AutomationServer') ktEdbALK  
    t_Q\uo}  
    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 .+.'TY--

    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: h<1pGQV  
    1. 在FRED脚本编辑界面找到参考. %}`zq8Q;  
    2. 找到Matlab Automation Server Type Library @ ,9cpaL3  
    3. 将名字改为MLAPP #?3oGrS Y  
    j=],n8_i  
    Rr%CP[bH  
    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。 UN8]>#\"`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: w>TlM*3D/  
    1. 创建Matlab服务器。 =Z(_lLNmh  
    2. 移动探测面对于前一聚焦面的位置。 R=co2 5  
    3. 在探测面追迹光线 H,Y+n)5  
    4. 在探测面计算照度 7_ G$&  
    5. 使用PutWorkspaceData发送照度数据到Matlab 57S!X|CE  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 M hwuh`v%  
    7. 用Matlab画出照度数据 x("V +y*  
    8. 在Matlab计算照度平均值 `B%IHr  
    9. 返回数据到FRED中 }2!=1|}
