    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。 YK_ 7ip.a[  
    1 MFbQs^  
    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: [Xkx_B  
    enableservice('AutomationServer', true) 6ujW Nf  
    enableservice('AutomationServer') X|dlt{Gf   
    vx =&QavL  
    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 hrk r'3lv  
    E .h*g8bXe  
    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: 6tZI["\   
    1. 在FRED脚本编辑界面找到参考. $4\j]RE!  
    2. 找到Matlab Automation Server Type Library 0GLM(JmK  
    3. 将名字改为MLAPP ".%k6W<n

    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。 mFeP9MfJ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: JF]JOI6.e  
    1. 创建Matlab服务器。  *CMx-_  
    2. 移动探测面对于前一聚焦面的位置。 bA 2pbjg=  
    3. 在探测面追迹光线 i b m4fa  
    4. 在探测面计算照度 xdPx{"C 3  
    5. 使用PutWorkspaceData发送照度数据到Matlab S:}7q2:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4H/OBR  
    7. 用Matlab画出照度数据 _1^'(5f$  
    8. 在Matlab计算照度平均值 ~DWl s.  
    9. 返回数据到FRED中 *8q.YuZ
