    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。 2gklGDJD  
    "0nsYE  
    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: Gjq7@F'  
    enableservice('AutomationServer', true) 'hWA&Xx +  
    enableservice('AutomationServer') 8a@k6OZ  
    8EkzSe  
    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 \tvL<U"'

    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: t90M]EAV  
    1. 在FRED脚本编辑界面找到参考. >`&2]Wc)  
    2. 找到Matlab Automation Server Type Library rZ+4kf6S   
    3. 将名字改为MLAPP *k#"@

    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。 P5B,= K>r

    现在将脚本代码公布如下,此脚本执行如下几个步骤: UkD\ma  
    1. 创建Matlab服务器。 bJ 6ivz  
    2. 移动探测面对于前一聚焦面的位置。 u59l)8=  
    3. 在探测面追迹光线 l i?@BHEf  
    4. 在探测面计算照度 ?[bE/Ya+S  
    5. 使用PutWorkspaceData发送照度数据到Matlab <]%6x[  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 /kyO,g$9  
    7. 用Matlab画出照度数据 9 4H')(
