    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。 N%\!eHxy  
    r-s.i+\  
    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 2\ ,n  
    enableservice('AutomationServer', true) :!\?yj{{  
    enableservice('AutomationServer') E}d@0C:  
    Re{vO&.  
    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 `r:n[N=Y&  
    CD'.bFO^+T  
    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: =r=YV-D.  
    1. 在FRED脚本编辑界面找到参考. f\}fUg 2  
    2. 找到Matlab Automation Server Type Library c-L1 Bkw  
    3. 将名字改为MLAPP 6;g"`l51

    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。 I65W^b4y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =1noT)gC R  
    1. 创建Matlab服务器。 .mzy?!w0q  
    2. 移动探测面对于前一聚焦面的位置。 "|yuP1;L  
    3. 在探测面追迹光线 r wtU@xsD  
    4. 在探测面计算照度 |UN0jR  
    5. 使用PutWorkspaceData发送照度数据到Matlab RCSG.*%%I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 iX]Vkx  
    7. 用Matlab画出照度数据 IvFxI#.ju  
    8. 在Matlab计算照度平均值 X\:;A{
