    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。 |xYr0C[Pq  
    f[1 s4Dp3-  
    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: cPunMHD  
    enableservice('AutomationServer', true) %Yw?!GvL[  
    enableservice('AutomationServer') ' _ZiZ4O  
    +%Z#!1u  
    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 Mbm'cM&}

    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: At<D36,^"  
    1. 在FRED脚本编辑界面找到参考. 1FA:"0lO  
    2. 找到Matlab Automation Server Type Library kB[l6`  
    3. 将名字改为MLAPP ]?S@g'Jd0Q

    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?JP=j

    现在将脚本代码公布如下,此脚本执行如下几个步骤: k%D|17I  
    1. 创建Matlab服务器。 :MaP58dhh  
    2. 移动探测面对于前一聚焦面的位置。 w`YN#G  
    3. 在探测面追迹光线 G22{',#r8  
    4. 在探测面计算照度 PQj'D <G  
    5. 使用PutWorkspaceData发送照度数据到Matlab D?.H|%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 t1`.M$  
    7. 用Matlab画出照度数据 ;{lb_du2:  
    8. 在Matlab计算照度平均值 "LNLM  
    9. 返回数据到FRED中 \X2r?
