    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。 =CWc`  
    u}^a^B$  
    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: u<$S>  
    enableservice('AutomationServer', true) A{G5Plrh  
    enableservice('AutomationServer') lp?i_p/z  
    7k.d|<mRv  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信  F|DR  
     <WO&$&  
    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: f34_?F<h  
    1. 在FRED脚本编辑界面找到参考. zuK/(qZ  
    2. 找到Matlab Automation Server Type Library d&O'r[S  
    3. 将名字改为MLAPP =PI^X\if88  
    [8 {_i?wY  
    pK-_R#  
    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。 [c,|Lw4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3WQRN_  
    1. 创建Matlab服务器。 ,R7=]~<io"  
    2. 移动探测面对于前一聚焦面的位置。 er&uC4Y]a  
    3. 在探测面追迹光线 Y{+zg9L*  
    4. 在探测面计算照度 =>gyc;{2K<  
    5. 使用PutWorkspaceData发送照度数据到Matlab  EGp~Vo-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 aeN }hG  
    7. 用Matlab画出照度数据 yBpW#1=  
    8. 在Matlab计算照度平均值 W@R$' r,@O  
    9. 返回数据到FRED中 rD:gN%B=
