    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。 9]^NAlno  
    rVDOco+w  
    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: z KNac[:  
    enableservice('AutomationServer', true) O\}w&BE:h  
    enableservice('AutomationServer') E&> 2=$~  
    MQl GEJ  
    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 H8qWY"<Vd

    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: 8l>YpS*S^  
    1. 在FRED脚本编辑界面找到参考. X-cP '"  
    2. 找到Matlab Automation Server Type Library =wFl(Q6J  
    3. 将名字改为MLAPP MUMB\K*$

    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。 @{@)gE

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3tCT"UvTD  
    1. 创建Matlab服务器。 Ba9"IXKH  
    2. 移动探测面对于前一聚焦面的位置。 ho}G]y  
    3. 在探测面追迹光线 fTd":F  
    4. 在探测面计算照度 HK`r9frn  
    5. 使用PutWorkspaceData发送照度数据到Matlab Kj#h9e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Eg$Er*)h8  
    7. 用Matlab画出照度数据 /D;cm  
    8. 在Matlab计算照度平均值 iy|xF~  
    9. 返回数据到FRED中 6\6g-1B`
