    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。 A 78{b^0*  
    z /=v@@tj  
    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+SL0  
    enableservice('AutomationServer', true) ] 2'~e,"O  
    enableservice('AutomationServer') M"V@>E\L  
    n\4+xZr  
    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 !JA63

    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: 7[\B{N9&W  
    1. 在FRED脚本编辑界面找到参考. ufOaD7  
    2. 找到Matlab Automation Server Type Library wVTo7o%U  
    3. 将名字改为MLAPP R_ }(p2

    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。 Qn7e6u@V

    现在将脚本代码公布如下,此脚本执行如下几个步骤: OZ&aTm :  
    1. 创建Matlab服务器。 ADDpm-]  
    2. 移动探测面对于前一聚焦面的位置。 :H{8j}"  
    3. 在探测面追迹光线 ~jaGf  
    4. 在探测面计算照度 O%I'   
    5. 使用PutWorkspaceData发送照度数据到Matlab w;"'l]W  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 QX4I+x~oo\  
    7. 用Matlab画出照度数据 lbY>R@5  
    8. 在Matlab计算照度平均值 LY MfoXp  
    9. 返回数据到FRED中 ;L7<mU
