    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。 0STtwfTr:  
    >B(%$jG Z  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: q !\Ht2$b  
    enableservice('AutomationServer', true) Gxu   
    enableservice('AutomationServer') 2%4dA$H#4w  
    gX<"-,5jc  
    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 Sx)b~*

    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: jqq96hP,  
    1. 在FRED脚本编辑界面找到参考. z-fP #.  
    2. 找到Matlab Automation Server Type Library )\!_`ob  
    3. 将名字改为MLAPP 'Lu7cb^  
    c:etJ  
     jL8[;*^G  
    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。 'qcLK>E

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $;NxO0$  
    1. 创建Matlab服务器。 xc)A`(g  
    2. 移动探测面对于前一聚焦面的位置。 [uCW8:e  
    3. 在探测面追迹光线 KdU!wsKfG  
    4. 在探测面计算照度 I>ks H  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;;rEv5 /  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 z%cq%P8g  
    7. 用Matlab画出照度数据 >qh8em  
    8. 在Matlab计算照度平均值 SA_5..  
    9. 返回数据到FRED中 -w nlJi1f
