    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。 OJbY\U  
    DJr 8<u  
    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: Nr|.]=K)5n  
    enableservice('AutomationServer', true) *xkbKkm  
    enableservice('AutomationServer') G"O %u|7  
    RRV@nDf   
    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  vF]?i

    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: 8W[QV  
    1. 在FRED脚本编辑界面找到参考. w^A8ZT0^7  
    2. 找到Matlab Automation Server Type Library @ns2$(wkm@  
    3. 将名字改为MLAPP zOg#=ql

    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。 {pd%I

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~Xh(JK]  
    1. 创建Matlab服务器。 y!blp>V6  
    2. 移动探测面对于前一聚焦面的位置。 e4khReF;  
    3. 在探测面追迹光线 n!ea)+^  
    4. 在探测面计算照度 <saS2.4  
    5. 使用PutWorkspaceData发送照度数据到Matlab AY [7yPP  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 lY?TF  
    7. 用Matlab画出照度数据 ;yBq'_e3  
    8. 在Matlab计算照度平均值 *q|.H9 K(  
    9. 返回数据到FRED中 8ENAif
