    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。 bT2b)nf  
    swntz  
    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: ;|5m;x/a  
    enableservice('AutomationServer', true) HE,# pj(D  
    enableservice('AutomationServer') ,nD:W  
    " +'E  
    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 rfpeX   
    T&   
    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: l}A8  
    1. 在FRED脚本编辑界面找到参考. 6Xu8~%i  
    2. 找到Matlab Automation Server Type Library %XM wjBM  
    3. 将名字改为MLAPP y+hC !-  
    y'(l]F1]  
    h/j+ b.|  
    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。 lU`]yL

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >jD,%yG  
    1. 创建Matlab服务器。 QWp,(Mv:r  
    2. 移动探测面对于前一聚焦面的位置。 SQ9s  
    3. 在探测面追迹光线 . T6fPEb  
    4. 在探测面计算照度 %6}S1fuA  
    5. 使用PutWorkspaceData发送照度数据到Matlab {7LO|E}7  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 eZ#nZB  
    7. 用Matlab画出照度数据 AL74q[>  
    8. 在Matlab计算照度平均值 M^JRHpTn  
    9. 返回数据到FRED中 HS =qK
