    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。 >>i@r@  
    2`GE  
    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: r|e-<t4.9L  
    enableservice('AutomationServer', true) dC\ZjZZ  
    enableservice('AutomationServer') @H>@[+S#  
    D?yG+%&9  
    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 %ek'~  
    cRd0S*QN2  
    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: jn >d*9u  
    1. 在FRED脚本编辑界面找到参考. $;M:TpX  
    2. 找到Matlab Automation Server Type Library mGUO6>g  
    3. 将名字改为MLAPP @yXfBML?]

    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。 C98]9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;$Y4xM`=m  
    1. 创建Matlab服务器。 )irRO8  
    2. 移动探测面对于前一聚焦面的位置。 #_Z$2L"U  
    3. 在探测面追迹光线 r:&` $8$  
    4. 在探测面计算照度 OouPj@r  
    5. 使用PutWorkspaceData发送照度数据到Matlab b^D$jY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -[U1]R  
    7. 用Matlab画出照度数据 x3qW0K8  
    8. 在Matlab计算照度平均值 /!^&;$A'  
    9. 返回数据到FRED中 o9xlu.QL{c
