    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。 & :W6O)uY  
    n9 bp0#K  
    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: _@?I)4n|  
    enableservice('AutomationServer', true) 08@4u L  
    enableservice('AutomationServer') ej7N5~!,s  
    3#""`]9H  
    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 rx]Q,;"  
    QHXpX9  
    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: e7iQG@i7  
    1. 在FRED脚本编辑界面找到参考. ;E{@)X..|  
    2. 找到Matlab Automation Server Type Library F*z>B >{)  
    3. 将名字改为MLAPP IY~I=}  
    MC-Z6l2  
    Ac*)z#H  
    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。 J#w=Z>oz<

    现在将脚本代码公布如下,此脚本执行如下几个步骤: u ?F},VL;  
    1. 创建Matlab服务器。 \2f?)id~  
    2. 移动探测面对于前一聚焦面的位置。 oN83`Z  
    3. 在探测面追迹光线 [N*S5^>1  
    4. 在探测面计算照度 .1h\r, #  
    5. 使用PutWorkspaceData发送照度数据到Matlab =JTwH>fD  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mWoN\Rwj  
    7. 用Matlab画出照度数据 b*Hk} !qH  
    8. 在Matlab计算照度平均值 j$u  
    9. 返回数据到FRED中 $^e_4]k
