    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。 thW<   
    XDz5b.,  
    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: %XTA;lrz  
    enableservice('AutomationServer', true) e/s(ojDW  
    enableservice('AutomationServer') Ph,- sR  
    ]}PV"|#K{c  
    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 pq! %?m]

    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: q/gB<p9  
    1. 在FRED脚本编辑界面找到参考. {`"#yl6"  
    2. 找到Matlab Automation Server Type Library `-UJ /{  
    3. 将名字改为MLAPP -?a<qa?$  
    l]_=:)" ]

    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。 }e]f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \\4Eh2 Y  
    1. 创建Matlab服务器。 l{WjDed  
    2. 移动探测面对于前一聚焦面的位置。 KEr\nKT1  
    3. 在探测面追迹光线 nU z7|y  
    4. 在探测面计算照度 :@3Wg3N  
    5. 使用PutWorkspaceData发送照度数据到Matlab =VP=|g  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 5OP`c<  
    7. 用Matlab画出照度数据 $t =O:  
    8. 在Matlab计算照度平均值 jE/oA<^  
    9. 返回数据到FRED中 u{f* M,k
