    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。 ln*_mM/Q%  
    km=d'VvnI  
    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: 2+'4m#@)  
    enableservice('AutomationServer', true) fEYo<@5c]  
    enableservice('AutomationServer') n B. u5  
    3x6@::s~  
    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 FJC}xEMcN  
    MVYf-'\^  
    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: {[tx^b  
    1. 在FRED脚本编辑界面找到参考. 2`V[Nb  
    2. 找到Matlab Automation Server Type Library -+H?0XN  
    3. 将名字改为MLAPP QZO9CLX 8k  
    =AVr<kP  
    ,Srj38p  
    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。 JZom#A. dt

    现在将脚本代码公布如下,此脚本执行如下几个步骤: `ZLA=oD  
    1. 创建Matlab服务器。 IuOY.c2.u  
    2. 移动探测面对于前一聚焦面的位置。 T0F!0O `  
    3. 在探测面追迹光线 WVkJ=r0Ny  
    4. 在探测面计算照度 iL\eMa  
    5. 使用PutWorkspaceData发送照度数据到Matlab vN8Xq+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 X ^\kI1  
    7. 用Matlab画出照度数据 _N2tf/C&=  
    8. 在Matlab计算照度平均值 A{(<#yRfg  
    9. 返回数据到FRED中 NkYU3[m$v
