    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。 Q[i/]  
    .E|Hk,c9  
    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: 6~\z]LZ  
    enableservice('AutomationServer', true) XJnDx 09h  
    enableservice('AutomationServer') K^AX=B  
    dwks"5l  
    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 O4FW/)gq  
    5,>1rd<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: ((rk)Q+;v  
    1. 在FRED脚本编辑界面找到参考. vTYI ez`g  
    2. 找到Matlab Automation Server Type Library 8Dpf{9Y-E  
    3. 将名字改为MLAPP MJ[#Gq\0R  
    [w l:"rm  
    ZjY_AbD  
    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。 k;:v~7VF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: L f[>U  
    1. 创建Matlab服务器。 %>'2E!%  
    2. 移动探测面对于前一聚焦面的位置。 ,LZ6Wu$P  
    3. 在探测面追迹光线 f&t]O$  
    4. 在探测面计算照度 VtF^; f  
    5. 使用PutWorkspaceData发送照度数据到Matlab xI'<4lo7Z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >%+ "-bY  
    7. 用Matlab画出照度数据 dz.]5R  
    8. 在Matlab计算照度平均值 ]@1YgV  
    9. 返回数据到FRED中 DR/qe0D
