    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。 0Z6geBMc  
    6u+aP  
    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: jO&*E 'pk  
    enableservice('AutomationServer', true) \/Mx|7<  
    enableservice('AutomationServer') iI IXv  
    ^r&)@R$V  
    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 :+PE1=v  
    + tMf&BZ  
    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: Q&I`uS=F  
    1. 在FRED脚本编辑界面找到参考. C{zp8 A(Dh  
    2. 找到Matlab Automation Server Type Library P Y^#hC5:  
    3. 将名字改为MLAPP ciS,  
    rYr*D[m]  
    |sReHt2)d  
    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。 /gZyl|kdy

    现在将脚本代码公布如下,此脚本执行如下几个步骤: (*9.GyK  
    1. 创建Matlab服务器。 dg24h7|]  
    2. 移动探测面对于前一聚焦面的位置。 m|qktLx  
    3. 在探测面追迹光线 9KXL6#h  
    4. 在探测面计算照度 ]A3  
    5. 使用PutWorkspaceData发送照度数据到Matlab zOs}v{8"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "ntP928  
    7. 用Matlab画出照度数据 c;$ 4}U4  
    8. 在Matlab计算照度平均值 LWF,w7v[L  
    9. 返回数据到FRED中 _?I{>:!|
