    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。 ^OGH5@"  
    E Ni%ge'":  
    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: [|P]St-  
    enableservice('AutomationServer', true) l{%Op\  
    enableservice('AutomationServer') {H"=PYR  
    7J)Hwl  
    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 ~-o^eI4_

    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: ;Wp`th!F  
    1. 在FRED脚本编辑界面找到参考. hVQ+ J!qD  
    2. 找到Matlab Automation Server Type Library ? ><   
    3. 将名字改为MLAPP AS/\IHZ\

    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。 tpy :o(H

    现在将脚本代码公布如下,此脚本执行如下几个步骤: P PIG?fK)  
    1. 创建Matlab服务器。 SE7 (+r  
    2. 移动探测面对于前一聚焦面的位置。 V~%WKQ  
    3. 在探测面追迹光线 #,|_d>p:  
    4. 在探测面计算照度 XxrO:$  
    5. 使用PutWorkspaceData发送照度数据到Matlab D%";!7u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 c]/O^/  
    7. 用Matlab画出照度数据 ?X5glDZ$  
    8. 在Matlab计算照度平均值 c#4ZDjvm6  
    9. 返回数据到FRED中 9zM4D
