    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。 \T4v|Pw\  
    %^?fMeI|Y  
    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: 5dx$HE&b)  
    enableservice('AutomationServer', true) I:=S 0&%)  
    enableservice('AutomationServer') M1k{t%M+S  
    !{ y@od@T  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 4GkWRu1  
    ]&o$b]  
    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: )1]ZtU  
    1. 在FRED脚本编辑界面找到参考. 3U<cWl@  
    2. 找到Matlab Automation Server Type Library V pE*(i$  
    3. 将名字改为MLAPP JgxtlYjl

    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。 @3>u@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: g{7.r-uu  
    1. 创建Matlab服务器。 5VfyU8)7X  
    2. 移动探测面对于前一聚焦面的位置。 ayn)5q/z  
    3. 在探测面追迹光线 .eS<Dbku<  
    4. 在探测面计算照度 i[O& )N,c  
    5. 使用PutWorkspaceData发送照度数据到Matlab ncZ+gzK|"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~Q Oe##  
    7. 用Matlab画出照度数据 |-fg j'  
    8. 在Matlab计算照度平均值 +>8'mf
