    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。 Bk}><H  
    a,Gxm!  
    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: JxjI]SF02  
    enableservice('AutomationServer', true) dDDGM:]  
        enableservice('AutomationServer') @R m-CWa  
    \*\R1_+  
    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 h8 G5GRD  
    3@n>*7/E  
    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: v_S4hz6w\  
    1. 在FRED脚本编辑界面找到参考. za'6Y*CGgX  
    2. 找到Matlab Automation Server Type Library s!+"yK  
        3. 将名字改为MLAPP rtQHWRUn  
         Kd3?I5t  
         nJ?^?M'F%  
    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。 dJ:MjQG`W

         z^nvMTC  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: Gq#~vr  
    1. 创建Matlab服务器。 !'=15&5@  
    2. 移动探测面对于前一聚焦面的位置。 8wH.et25k  
    3. 在探测面追迹光线 Zs2-u^3&  
    4. 在探测面计算照度 i{^Z1;Yl  
    5. 使用PutWorkspaceData发送照度数据到Matlab <P%}|@  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 >%Ee#m  
    7. 用Matlab画出照度数据 I NSkgOo  
    8. 在Matlab计算照度平均值 P%Ay3cR+E  
    9. 返回数据到FRED中 f-2$ L
