    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。 ?* ~4~ZE E  
    c ,#=In2  
    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: "tT4Cb3  
    enableservice('AutomationServer', true) hq4&<Zr(  
    enableservice('AutomationServer') :E{)yT  
    \HxF?i "   
    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 FM%WMyb[

    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: |keU+De  
    1. 在FRED脚本编辑界面找到参考. &$ }6:  
    2. 找到Matlab Automation Server Type Library -8)C6"V{  
    3. 将名字改为MLAPP Q>[{9bI4QP  
    [ `|t(E'  
    i`YZ;L L  
    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。 |Ja5O

    现在将脚本代码公布如下,此脚本执行如下几个步骤: _I)TO_L;  
    1. 创建Matlab服务器。 '`tFZfT  
    2. 移动探测面对于前一聚焦面的位置。 NXLb'mH~  
    3. 在探测面追迹光线 xqdkc^b  
    4. 在探测面计算照度 mR2"dq;U  
    5. 使用PutWorkspaceData发送照度数据到Matlab g3s5ra[  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Q?hf2iw  
    7. 用Matlab画出照度数据 bv41et+Kb  
    8. 在Matlab计算照度平均值 =H: N!!:  
    9. 返回数据到FRED中 k %{q q v
