    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。 j B.ZF7q  
    7ThGF  
    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: ZJZKCdT@  
    enableservice('AutomationServer', true) [H-r0Ah  
    enableservice('AutomationServer') h#EksX  
    J/-&Fa\(  
    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 B'@a36  
    v +$3Z5  
    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: q3SYlL'a  
    1. 在FRED脚本编辑界面找到参考. y?r:`n  
    2. 找到Matlab Automation Server Type Library CLn}BxgD  
    3. 将名字改为MLAPP z[E gMS!  
    XFS"~{

    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。 dI$U{;t

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ue/GB+U  
    1. 创建Matlab服务器。 M~o\K'  
    2. 移动探测面对于前一聚焦面的位置。 +CQ$-3  
    3. 在探测面追迹光线 _7k6hVQ  
    4. 在探测面计算照度 q%rfKHMA50  
    5. 使用PutWorkspaceData发送照度数据到Matlab [Y%H8}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [WAnII  
    7. 用Matlab画出照度数据 0/g 0=dW=  
    8. 在Matlab计算照度平均值 5VLJ:I?0O  
    9. 返回数据到FRED中 GELx S!
