    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。 H)NT2@%{P  
    WGI4DzKa  
    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: Uc5BNk7<=  
    enableservice('AutomationServer', true) rB.LG'GG]  
    enableservice('AutomationServer') CChCxB  
    LAv!s/O$=  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Yjix]lUXVf  
    z?Qt%1q  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: R% )7z)~  
    1. 在FRED脚本编辑界面找到参考. kqp*o+Oz',  
    2. 找到Matlab Automation Server Type Library !T1)tGrH  
    3. 将名字改为MLAPP ;09U*S$eK  
    K5:>  
    h}f l:J1C  
    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。 ^26}8vt

    现在将脚本代码公布如下,此脚本执行如下几个步骤: m7NrS?7  
    1. 创建Matlab服务器。 <wO8=bem  
    2. 移动探测面对于前一聚焦面的位置。 +<\.z*  
    3. 在探测面追迹光线 lb[\Lzdvmu  
    4. 在探测面计算照度 !F~*Q2PZ9  
    5. 使用PutWorkspaceData发送照度数据到Matlab E:S (v  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +G lb  
    7. 用Matlab画出照度数据 SZm&2~|J  
    8. 在Matlab计算照度平均值 ew\ZFqA;  
    9. 返回数据到FRED中 U+'h~P'4
