    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。 Kf#!IY][  
    n~j[Pw  
    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: _+iz?|U  
    enableservice('AutomationServer', true) <>s\tJ  
    enableservice('AutomationServer') MFuI&u!g:  
    6l'y  
    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 UI C? S  
    8 -A7  
    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: $:!T/*p*  
    1. 在FRED脚本编辑界面找到参考. bl_WN|SQ  
    2. 找到Matlab Automation Server Type Library PBtU4)  
    3. 将名字改为MLAPP NCt sx /C  
    yan[{h]EZ  
    Ir #V2]$  
    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。 #Ca's'j&f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: .N&}<T[  
    1. 创建Matlab服务器。 :n9~H+!  
    2. 移动探测面对于前一聚焦面的位置。 Y{RB\}f(  
    3. 在探测面追迹光线 !#1A7[WN  
    4. 在探测面计算照度 30+l0\1  
    5. 使用PutWorkspaceData发送照度数据到Matlab =hIT?Z6A  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 y51D-vj  
    7. 用Matlab画出照度数据 yMl'1W  
    8. 在Matlab计算照度平均值 5C1Rub)  
    9. 返回数据到FRED中 L]N2r MM
