    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。 GZ]; U] _  
    ,Mwj`fgh  
    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: 8W"~>7/>D  
    enableservice('AutomationServer', true) Mc6?]wDB]  
    enableservice('AutomationServer') =ITMAC\  
    vF K&.J  
    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+S;u=CKx  
    q<b;xx  
    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: pFg9-xd%  
    1. 在FRED脚本编辑界面找到参考. XoaBX2  
    2. 找到Matlab Automation Server Type Library xla9:*pPn  
    3. 将名字改为MLAPP )nS;]7pB@

    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。 f,Sybf/uHh

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Z;W`deA  
    1. 创建Matlab服务器。 J~:/,'Ea  
    2. 移动探测面对于前一聚焦面的位置。 -<i&`*zG  
    3. 在探测面追迹光线 $N=A,S  
    4. 在探测面计算照度 ![iAALPNl  
    5. 使用PutWorkspaceData发送照度数据到Matlab !_cT_ WHty  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 cV5Lp4wY?  
    7. 用Matlab画出照度数据 t\]CdH`+  
    8. 在Matlab计算照度平均值 o=2y`Eq  
    9. 返回数据到FRED中 xgtdmv%
