    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。 $&a`zffG  
    c)E'',-J_2  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: +A:}5{  
    enableservice('AutomationServer', true) i uN8gHx  
    enableservice('AutomationServer') CdEJ/G:  
    ):.]4n{L  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 yTZbJx?m  
    [q(7Jv  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ;{Ovqo|  
    1. 在FRED脚本编辑界面找到参考. 9$)4C|  
    2. 找到Matlab Automation Server Type Library PDGh\Y[AK,  
    3. 将名字改为MLAPP ^8fO3<Jg

    9I pjY~or  
    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。 kB  :")$

    现在将脚本代码公布如下,此脚本执行如下几个步骤: o9Agx{'oV  
    1. 创建Matlab服务器。 D.\p7 NJ  
    2. 移动探测面对于前一聚焦面的位置。  =v8#@$  
    3. 在探测面追迹光线 9D 0ujup  
    4. 在探测面计算照度 T?% F  
    5. 使用PutWorkspaceData发送照度数据到Matlab {v2Q7ZO-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 UQhfR}(  
    7. 用Matlab画出照度数据 85H8`YwPh  
    8. 在Matlab计算照度平均值 Z7%>O:@z  
    9. 返回数据到FRED中 -bE{yT)7
