    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。 8Gs{Zfp!D  
    t[0gN:s  
    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: Ue~M .LZb  
    enableservice('AutomationServer', true) L# (o(4g2  
        enableservice('AutomationServer') N{oD1%  
    C3WqUf<8`{  
    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 +ZXk0sP_<  
    6Pd;I,k  
    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: i wK,XnIR  
    1. 在FRED脚本编辑界面找到参考. 7pr@aA"vgj  
    2. 找到Matlab Automation Server Type Library S,qsCnz  
        3. 将名字改为MLAPP yg/.=M

    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。 NcFHvK

    现在将脚本代码公布如下,此脚本执行如下几个步骤: JAc-5e4  
    1. 创建Matlab服务器。 ~eE2!/%9  
    2. 移动探测面对于前一聚焦面的位置。 'TezUBRAz  
    3. 在探测面追迹光线 q[7C,o>/  
    4. 在探测面计算照度 f~8Xue,l"  
    5. 使用PutWorkspaceData发送照度数据到Matlab $Jx] FZDQ  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 WVp14Z?k  
    7. 用Matlab画出照度数据 "J7=3$CA  
    8. 在Matlab计算照度平均值 =d&  
    9. 返回数据到FRED中 </Q<*@p?
