    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。 =FwFqjvl  
    jRgv 8n  
    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: :Ur%.0  
    enableservice('AutomationServer', true) P_b00",S  
    enableservice('AutomationServer') {`J7>K  
    bz}T}nj  
    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 T \0e8"iZ

    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: =3 -G  
    1. 在FRED脚本编辑界面找到参考. U6M4}q(N]  
    2. 找到Matlab Automation Server Type Library t$Qav>D  
    3. 将名字改为MLAPP kP [ Y

    C #TS  
    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。 >@rp]xx

    现在将脚本代码公布如下,此脚本执行如下几个步骤: E; RI.6y  
    1. 创建Matlab服务器。 {a(YV\^y|H  
    2. 移动探测面对于前一聚焦面的位置。 XqJ@NgsY  
    3. 在探测面追迹光线 ^-=,q.[7  
    4. 在探测面计算照度 z` gR*+  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8.9S91]=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 N'[^n,\(:  
    7. 用Matlab画出照度数据 nnr(\r~  
    8. 在Matlab计算照度平均值 C:P,q6  
    9. 返回数据到FRED中 1lMU('r%
