    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。 P _Gu~B!Y  
    FD~uUZTM  
    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: |P9MhfN  
    enableservice('AutomationServer', true) ]~3a~  
    enableservice('AutomationServer') b,ZBol|X  
    6~!7?FK  
    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 R4[|f0l}s  
    =`MQKh,  
    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: #K-O<:s=y  
    1. 在FRED脚本编辑界面找到参考. Lrt~Q:z2u  
    2. 找到Matlab Automation Server Type Library rV%;d[LB  
    3. 将名字改为MLAPP qpf|.m  
    N- <,wUxf  
    ~O /B  
    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。 Ql}#mC.>/

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T-oUcuQB  
    1. 创建Matlab服务器。 ZD?LsD3  
    2. 移动探测面对于前一聚焦面的位置。 >Zm|R|{BE  
    3. 在探测面追迹光线 8"wavh|g4  
    4. 在探测面计算照度 Z2]\k|%<Fa  
    5. 使用PutWorkspaceData发送照度数据到Matlab f0{ tBD!%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4kNSF  
    7. 用Matlab画出照度数据 i94)DWZ^  
    8. 在Matlab计算照度平均值 i#U_g:~wC  
    9. 返回数据到FRED中 '<C#"2
