    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。 /#-,R,Q  
    Ez zTJ>  
    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: 9nT?|n]>  
    enableservice('AutomationServer', true) /~H[= Pf  
    enableservice('AutomationServer') gIV3n#-{L  
    Y5n z?a  
    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 .@y{)/

    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: JfI aOhKs]  
    1. 在FRED脚本编辑界面找到参考. o\_ Td  
    2. 找到Matlab Automation Server Type Library *0=fT}&!  
    3. 将名字改为MLAPP [MV`pF)x

    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。 r/UYC"K3

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pBlRd{#fL  
    1. 创建Matlab服务器。 gJ]Cq/gC  
    2. 移动探测面对于前一聚焦面的位置。 4a\n4KO X  
    3. 在探测面追迹光线 mZ`1JO9  
    4. 在探测面计算照度 4 hL`=[AB  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6P0y-%[Gk  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 TF BYY{Y  
    7. 用Matlab画出照度数据 XxmJP5  
    8. 在Matlab计算照度平均值 @)9REA(U  
    9. 返回数据到FRED中 5gO /-Zj
