    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。 D[>:az `  
    !zK"y[V  
    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: 3~sV-  
    enableservice('AutomationServer', true) > )4~,-;k  
    enableservice('AutomationServer') r*{.|>me  
    [r2V+b.C  
    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 Mc?_2<u-  
    /[/L%;a'p  
    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: =ls+vH40&  
    1. 在FRED脚本编辑界面找到参考. nk!uO^  
    2. 找到Matlab Automation Server Type Library / B!j`UK  
    3. 将名字改为MLAPP Ox)<"8M

    }oD^tU IK  
    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。 x1~AY/)v

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ftn10TO*  
    1. 创建Matlab服务器。 rw)!>j+&A  
    2. 移动探测面对于前一聚焦面的位置。 W(62.3d~}?  
    3. 在探测面追迹光线 l9QIlTc7  
    4. 在探测面计算照度 ",~ZO<P  
    5. 使用PutWorkspaceData发送照度数据到Matlab LDegJer-v  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 H0b{`!'Fs:  
    7. 用Matlab画出照度数据 U2`:'  
    8. 在Matlab计算照度平均值 tO&n$$  
    9. 返回数据到FRED中 m2m ;|rr
