    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。 BS_ 3|  
    hN3*]s;/6z  
    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: &Is}<Ew  
    enableservice('AutomationServer', true) \=yWJ  
    enableservice('AutomationServer') g]V_)}  
    kU {>hG4  
    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 Zr%,F[j?  
    nH=8I~jp  
    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: ls9 28  
    1. 在FRED脚本编辑界面找到参考. Uf ?._&:  
    2. 找到Matlab Automation Server Type Library Ac2,A>  
    3. 将名字改为MLAPP ~.*G%TW &V

    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。 eq!>~: #

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 7^2  
    1. 创建Matlab服务器。 Q/[g|"  
    2. 移动探测面对于前一聚焦面的位置。 '=Z]mi/aw  
    3. 在探测面追迹光线 k"z ~>  
    4. 在探测面计算照度 |g@n'^]  
    5. 使用PutWorkspaceData发送照度数据到Matlab @  gv^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 fVXZfq6  
    7. 用Matlab画出照度数据 @5rl;C  
    8. 在Matlab计算照度平均值 o^!_S5zKe.  
    9. 返回数据到FRED中 RZgklEU
