    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。 4'Zp-k?5`  
    a@*\o+Su  
    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: 5PnDN\  
    enableservice('AutomationServer', true) "wHFN>5B  
    enableservice('AutomationServer') -PQv ?5  
    4a]P7fx-  
    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 ` ~`k_7t.

    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: OBAi2Vw  
    1. 在FRED脚本编辑界面找到参考. 8&aq/4:q0  
    2. 找到Matlab Automation Server Type Library {.\TtE  
    3. 将名字改为MLAPP eGHaY4|  
    "-J -k=  
    "w.3Q96r  
    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。 tNX|U:Y*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: I 2|Bg,e  
    1. 创建Matlab服务器。 # N cK X  
    2. 移动探测面对于前一聚焦面的位置。 C73 kJa  
    3. 在探测面追迹光线 &9)\wnOS  
    4. 在探测面计算照度 |H+Wed|  
    5. 使用PutWorkspaceData发送照度数据到Matlab {!dVDf_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :[!j?)%>  
    7. 用Matlab画出照度数据 \K!VNB>h  
    8. 在Matlab计算照度平均值 5[u]E~Fl}  
    9. 返回数据到FRED中 y;H-m>*%
