    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。 |E"Xavi>  
    3"HGEUqA  
    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)SM),bE[  
    enableservice('AutomationServer', true) oqm  
    enableservice('AutomationServer') T_(qN;_  
    ?"5~Wwp.T  
    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 W?SP .-I  
    =# k<Kw#  
    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: =}B4I  
    1. 在FRED脚本编辑界面找到参考.  5xG|35Pj  
    2. 找到Matlab Automation Server Type Library 5HWwl.D  
    3. 将名字改为MLAPP E.?E~}z

    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。 I rtF4ia.

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Bf D,z  
    1. 创建Matlab服务器。 /}h71V!  
    2. 移动探测面对于前一聚焦面的位置。 NqQM! B]  
    3. 在探测面追迹光线 2LhfXBWf  
    4. 在探测面计算照度 ak~=[7Nv  
    5. 使用PutWorkspaceData发送照度数据到Matlab "N?%mCPI  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +YGw4{\EL  
    7. 用Matlab画出照度数据 VEFwqB1l  
    8. 在Matlab计算照度平均值 *F26}q  
    9. 返回数据到FRED中 ` <l/GwtAJ
