    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。 #|acRZ9 }  
    ]0myoWpi3  
    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: 4Pr@<S"U  
    enableservice('AutomationServer', true) $ Q*^c"&  
    enableservice('AutomationServer') J8PZVeWx  
    LKu ,H  
    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 fBct%M 3

    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: 9I*`~il>{  
    1. 在FRED脚本编辑界面找到参考. D? FWSv  
    2. 找到Matlab Automation Server Type Library jo[U6t+pj7  
    3. 将名字改为MLAPP ^ &VN=Y6z

    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。 qJ<Ghd`8v

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ,:?=j80m  
    1. 创建Matlab服务器。 +We=- e7  
    2. 移动探测面对于前一聚焦面的位置。 hO4* X  
    3. 在探测面追迹光线 ]gB:ht  
    4. 在探测面计算照度 aUEnQ%YU"  
    5. 使用PutWorkspaceData发送照度数据到Matlab !_j6\r=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >d5L4&r  
    7. 用Matlab画出照度数据 6yXMre)YV  
    8. 在Matlab计算照度平均值 NIxtT>[+3  
    9. 返回数据到FRED中 /3Cd P'c
