    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。 eTay/i<-  
    j; R20xf0  
    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: `uZMln @  
    enableservice('AutomationServer', true) $15H_X*!  
    enableservice('AutomationServer') R[)bGl6#  
    0s\ -iub=d  
    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 .!Kqcz% A  
    5&O%0`t  
    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: KY%{'"'u  
    1. 在FRED脚本编辑界面找到参考. H8=:LF  
    2. 找到Matlab Automation Server Type Library pOh<I {r1  
    3. 将名字改为MLAPP /J&ks>St  
    `j!_tE`

    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。 E!BzE_|i

    现在将脚本代码公布如下,此脚本执行如下几个步骤: _zi| GD  
    1. 创建Matlab服务器。 =8%*Rrj^  
    2. 移动探测面对于前一聚焦面的位置。 GN:|b2 "  
    3. 在探测面追迹光线 s9OW.i]zX  
    4. 在探测面计算照度 ek]nLN  
    5. 使用PutWorkspaceData发送照度数据到Matlab V|[NL4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 s@{~8cHgU  
    7. 用Matlab画出照度数据 _[-W*,xJ)  
    8. 在Matlab计算照度平均值 xSNGf@1b  
    9. 返回数据到FRED中 K=nDC.
