    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。 'OP0#`6`  
    ;sAGTq  
    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: [Eu) ~J*  
    enableservice('AutomationServer', true) 5n}<V-yJ*m  
    enableservice('AutomationServer') .n YlYY'   
    `G`R|B  
    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 62_k`)k

    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: Xz)F-C27h  
    1. 在FRED脚本编辑界面找到参考. Ny/eYF#  
    2. 找到Matlab Automation Server Type Library g.hYhg'KUh  
    3. 将名字改为MLAPP +ls`;f  
    Vym0|cW

    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。 GCO: !,1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: y'4Qt.1ukN  
    1. 创建Matlab服务器。 "uIaKb  
    2. 移动探测面对于前一聚焦面的位置。 Y.Z:H!P);$  
    3. 在探测面追迹光线 U 887@-!3  
    4. 在探测面计算照度 Gvh"3|u ?z  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5BXku=M  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 BYM6cp+S  
    7. 用Matlab画出照度数据 L_vl%ii-  
    8. 在Matlab计算照度平均值 h ka_Fo  
    9. 返回数据到FRED中 *DfOm`m
