    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。 "2'4b  
    Y["aw&;#O\  
    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: 0+3_CS++r  
    enableservice('AutomationServer', true) fl@=h[g#t  
    enableservice('AutomationServer') }^Ymg7wA  
    p9X{E%A<:  
    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 7l%]O}!d)

    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: ;r8< Ed  
    1. 在FRED脚本编辑界面找到参考. t_xO-fT)  
    2. 找到Matlab Automation Server Type Library ^+ J3E4  
    3. 将名字改为MLAPP *C~$<VYI

    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。 qX9x#92

    1. 创建Matlab服务器。 `/"*_AKAI  
    2. 移动探测面对于前一聚焦面的位置。 n=F|bW  
    3. 在探测面追迹光线 xcHuH -}  
    4. 在探测面计算照度 BT*z^Z H  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6lAHB*`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 cM?i _m  
    7. 用Matlab画出照度数据 Z>l%:;H  
    8. 在Matlab计算照度平均值 D[H #W[  
    9. 返回数据到FRED中 N+N98~Y`P
