    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。 0Ci/-3HV!  
    VN`fZ5*d~  
    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: X-kOp9/.  
    enableservice('AutomationServer', true) #v xq|$e  
    enableservice('AutomationServer') ]d@>vzCO  
    gGUKB2)  
    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 >5:O%zQ@  
    $7c,<=  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: !|i #g$  
    1. 在FRED脚本编辑界面找到参考. z\A ),;  
    2. 找到Matlab Automation Server Type Library uf9&o#  
    3. 将名字改为MLAPP D9A%8o  
    i,a"5DR8

    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。 %Q0R] Hg

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fz:(mZ%  
    1. 创建Matlab服务器。 ^Y%_{   
    2. 移动探测面对于前一聚焦面的位置。 2M'dT Xz  
    3. 在探测面追迹光线 $Oy&PO e  
    4. 在探测面计算照度  16~E  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^N|8 B?Vg  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _W_< bI34  
    7. 用Matlab画出照度数据 kDWEgnXK,v  
    8. 在Matlab计算照度平均值 S#y[_C?H  
    9. 返回数据到FRED中 OM&GypP6&
