    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。 .c^ ggy%  
    E15vq6DKF  
    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: 0G <hn8>  
    enableservice('AutomationServer', true) BPqGJ7@  
    enableservice('AutomationServer') yMc:n "-[  
    _TUt9}  
    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 "BKeot[""p  
    >r)X:K+I  
    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: <w>/^|]#  
    1. 在FRED脚本编辑界面找到参考. 8L5!T6+D&  
    2. 找到Matlab Automation Server Type Library B/J&l  
    3. 将名字改为MLAPP o5Y2vmz?9  
    6al=Cwf  
    9p@C4oen  
    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。 ~AG$5!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =q(GHg;'  
    1. 创建Matlab服务器。 ~u&|G$1!0  
    2. 移动探测面对于前一聚焦面的位置。 \aP6_g:N}  
    3. 在探测面追迹光线 sT1&e5`W  
    4. 在探测面计算照度 C+F*690h  
    5. 使用PutWorkspaceData发送照度数据到Matlab Qn:kz*:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _2hXa!yO  
    7. 用Matlab画出照度数据 @!Hr|k|  
    8. 在Matlab计算照度平均值 b-@\R\T  
    9. 返回数据到FRED中 Q0_>'sEM
