    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。 F~C9,`#Wf@  
    u#>*"4Q  
    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: Qgel^"t]i  
    enableservice('AutomationServer', true) ?F!='6D}b  
    enableservice('AutomationServer') O! t> @%)  
    +OTNn@!9  
    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 mv0JD(  
    'u)zQAaw.  
    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: w4"4(SR.  
    1. 在FRED脚本编辑界面找到参考. j)vfI>  
    2. 找到Matlab Automation Server Type Library SFaG`T=  
    3. 将名字改为MLAPP > ]()#z  
     > h>

    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。 Js'#=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =Ll:Ba Q  
    1. 创建Matlab服务器。 /^XGIQ/W  
    2. 移动探测面对于前一聚焦面的位置。 mh8{`W&  
    3. 在探测面追迹光线 P_:~!+W,  
    4. 在探测面计算照度 ;<?mMi@<E  
    5. 使用PutWorkspaceData发送照度数据到Matlab $vQ#ah/k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LKx<hl$O  
    7. 用Matlab画出照度数据 b-Q%c xJ  
    8. 在Matlab计算照度平均值 FkS$x'~2$  
    9. 返回数据到FRED中 hh$V[/iK
