    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。 fILINW{Yk)  
    DGz'Dn  
    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: @0;9.jml,  
    enableservice('AutomationServer', true) $6L gaz  
    enableservice('AutomationServer') h \hQ  
    V<$g^Vb  
    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 rUvqAfE&+  
    u-=S_e  
    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|Yw a=  
    1. 在FRED脚本编辑界面找到参考. d+[yW7%J  
    2. 找到Matlab Automation Server Type Library cpF\^[D  
    3. 将名字改为MLAPP w}c1zpa  
    I,(m\NalK  
    DN2K4%cM%'  
    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。 r :{2}nE

    现在将脚本代码公布如下,此脚本执行如下几个步骤: MUh )  
    1. 创建Matlab服务器。 BNw^ _j1  
    2. 移动探测面对于前一聚焦面的位置。 #I|Vyufw  
    3. 在探测面追迹光线 I\&..e0l  
    4. 在探测面计算照度 OB)Vk  
    5. 使用PutWorkspaceData发送照度数据到Matlab " ;_bB"q*  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \K.i8f,  
    7. 用Matlab画出照度数据 wj!p6D;;S  
    8. 在Matlab计算照度平均值 [u;]J*  
    9. 返回数据到FRED中 FbO-K-
