    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。 9l7 youZ]  
    piiO5fK|  
    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: kZ 9n@($B  
    enableservice('AutomationServer', true) }% ?WS  
    enableservice('AutomationServer') >LB x\/  
    ZW8;?# _  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 CwfGp[|}e  
    gem+$TFq  
    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: -(.\> F  
    1. 在FRED脚本编辑界面找到参考. <=~'Pd-f(  
    2. 找到Matlab Automation Server Type Library  M Xl!  
    3. 将名字改为MLAPP `JG7Pl/ih  
    O`(it %Ho!

    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。 5s2/YG=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0EP8MRSR  
    1. 创建Matlab服务器。 3qH`zYgh  
    2. 移动探测面对于前一聚焦面的位置。 #*K!@X  
    3. 在探测面追迹光线 QmB,~x{j>  
    4. 在探测面计算照度 g.O? 1bebe  
    5. 使用PutWorkspaceData发送照度数据到Matlab cE]#23  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 12%4>2}~>  
    7. 用Matlab画出照度数据 |=}v^o ZC  
    8. 在Matlab计算照度平均值 5'O.l$)y  
    9. 返回数据到FRED中 jLf87
