    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。  D}98ZKi  
    xR/CP.dg  
    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: 10Ik_L='  
    enableservice('AutomationServer', true) "w'pIUQ3,  
    enableservice('AutomationServer') b0{i +R  
    &*=!B9OBI  
    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 6]?mjG6  
    ]?tRO  
    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: 6dRhK+|  
    1. 在FRED脚本编辑界面找到参考. *c$[U{Px  
    2. 找到Matlab Automation Server Type Library vW1^  
    3. 将名字改为MLAPP rPaJ<>Kz  
    ?e$&=FC0;

    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。 Hd|[>4Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: QxYm3x5  
    1. 创建Matlab服务器。 $r/$aq=K  
    2. 移动探测面对于前一聚焦面的位置。 V`^*Z}d9  
    3. 在探测面追迹光线 da7"Q{f+  
    4. 在探测面计算照度 $[>{s9E  
    5. 使用PutWorkspaceData发送照度数据到Matlab .Vbd-jr'M  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {dpC;jsW1  
    7. 用Matlab画出照度数据 eiKY az  
    8. 在Matlab计算照度平均值 h0tiWHw  
    9. 返回数据到FRED中 ~~W.]>f
