    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。 qhGz2<}_j  
    8)1q,[:M  
    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: '/u|32  
    enableservice('AutomationServer', true) mxgT}L0i  
    enableservice('AutomationServer') UF!qp  
    D;0>-  
    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 /=p[k^A  
    $UH:r  
    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: $M)i]ekm  
    1. 在FRED脚本编辑界面找到参考. c36p+6rJk=  
    2. 找到Matlab Automation Server Type Library U_*, XLU  
    3. 将名字改为MLAPP !YAX.e  
    5,gT|4|B\g  
    RD:G 9[  
    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。 MWv@]P_0p!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -H6[{WVW!  
    1. 创建Matlab服务器。 1@L18%h  
    2. 移动探测面对于前一聚焦面的位置。 uM`i!7}  
    3. 在探测面追迹光线 %JE>Z]  
    4. 在探测面计算照度 t <` As6}  
    5. 使用PutWorkspaceData发送照度数据到Matlab "KP]3EyPc  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <4Gy~?  
    7. 用Matlab画出照度数据 RdPk1?}K  
    8. 在Matlab计算照度平均值 l%EvXdZuOy  
    9. 返回数据到FRED中 GFdbwn5B
