    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。 g_3Ozy  
    n v ?u  
    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: -]Ny-[P  
    enableservice('AutomationServer', true) hRQw]  
    enableservice('AutomationServer') QQ/9ZI5  
    m;J'y2h =$  
    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 e>UU/Ks  
    I{$TMkh[  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 0}` 0!Kv  
    1. 在FRED脚本编辑界面找到参考. i'B$Xr  
    2. 找到Matlab Automation Server Type Library {(IHHA>  
    3. 将名字改为MLAPP 0Of6$`

    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。 7*kTu0m

    3. 在探测面追迹光线 k]9y+WC2  
    4. 在探测面计算照度 n0FzDQt26  
    5. 使用PutWorkspaceData发送照度数据到Matlab Elt" tJ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 dG!)<  
    7. 用Matlab画出照度数据 RNopx3  
    8. 在Matlab计算照度平均值 Us\Nmso z  
    9. 返回数据到FRED中 e F(oHn,
