    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。 B/f0P(7  
    +Lm4kA+aE5  
    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: FjfN3#qlg  
    enableservice('AutomationServer', true) @~ Dh'w2q  
    enableservice('AutomationServer') GV|9H]_,I  
    w?vVVA  
    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 9-1#( Y6S  
    9v )%dO.  
    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: 0BPMmk  
    1. 在FRED脚本编辑界面找到参考. 7v}x?I  
    2. 找到Matlab Automation Server Type Library WKM)*@#,  
    3. 将名字改为MLAPP V~MiO.B  
    bUy,5gk-  
    .\3`2  
    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。 eJ8]g49mD6

    1. 创建Matlab服务器。 4EP<tV  
    2. 移动探测面对于前一聚焦面的位置。 ws/63 d*  
    3. 在探测面追迹光线 f&@BKx  
    4. 在探测面计算照度 }u{gR:lZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab :\~+#/=:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 E:E4ulak  
    7. 用Matlab画出照度数据 =1;=  
    8. 在Matlab计算照度平均值 9%)=`W  
    9. 返回数据到FRED中 "VxWj}+]
