    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。 $h8,QPy  
    ~M LBO  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: L QA6iZBP  
    enableservice('AutomationServer', true) L$ ZZ]?7j  
    enableservice('AutomationServer') 2U`g[1  
    nSeb?|$D6  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Kma-W{vGD  
     eAbp5}B  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: G;v3kGn  
    1. 在FRED脚本编辑界面找到参考. =U+_;;F=  
    2. 找到Matlab Automation Server Type Library ) >8k8E  
    3. 将名字改为MLAPP #kPsg9Y  
    O (YvE  
    5u&hp  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 d m$iiRY

    现在将脚本代码公布如下,此脚本执行如下几个步骤: IltU6=]"l  
    1. 创建Matlab服务器。 [p&2k&.XYe  
    2. 移动探测面对于前一聚焦面的位置。 k{w  
    3. 在探测面追迹光线 ]:F?k#c  
    4. 在探测面计算照度 OA{PKC  
    5. 使用PutWorkspaceData发送照度数据到Matlab LQ.0"6oj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Q[UYNQ0w  
    7. 用Matlab画出照度数据 y`p(}X`>  
    8. 在Matlab计算照度平均值 B5 H=#  
    9. 返回数据到FRED中 Cy'! >
