    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。 vcdVck@  
    cZ_)'0  
    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: =( |%%,3  
    enableservice('AutomationServer', true) D<69xT,  
    enableservice('AutomationServer') Is4,QnY_[  
    Cg]|x+  
    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 I9 zs  
    h,R Isq;`  
    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: +o`%7r(R  
    1. 在FRED脚本编辑界面找到参考. k!x|oC0  
    2. 找到Matlab Automation Server Type Library 3h:~NL  
    3. 将名字改为MLAPP L0"|4=

    Uo >aQk  
    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。 %urvX$r4K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Axsezr/  
    1. 创建Matlab服务器。 5zBA]1PY  
    2. 移动探测面对于前一聚焦面的位置。 F2}Fuupb.  
    3. 在探测面追迹光线 ]]K?Q )9x  
    4. 在探测面计算照度 Kj4BVs  
    5. 使用PutWorkspaceData发送照度数据到Matlab t$nJmfzm  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 > pb}@\;:  
    7. 用Matlab画出照度数据 Gw3+TvwU+Q  
    8. 在Matlab计算照度平均值 ;/$pxD  
    9. 返回数据到FRED中 -+@N/d5
