    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。 +]wuJSxc  
    tY/vL^mi  
    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: i!H!;z#  
    enableservice('AutomationServer', true) w4};q%OBj  
    enableservice('AutomationServer') W6/ @W  
    S]>wc yy=n  
    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 -j2 (R?a  
    u'5`[U -!  
    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: c z'5iK  
    1. 在FRED脚本编辑界面找到参考. <PD?f/4 /  
    2. 找到Matlab Automation Server Type Library @4GA^h  
    3. 将名字改为MLAPP u?H 2%hD

    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。 VD7i52xS

    现在将脚本代码公布如下,此脚本执行如下几个步骤: vT{kL

    3. 在探测面追迹光线 d IB }_L  
    4. 在探测面计算照度 3'I^lc  
    5. 使用PutWorkspaceData发送照度数据到Matlab MXp3g@Cz  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Nh!_l  
    7. 用Matlab画出照度数据 [AzO:A  
    8. 在Matlab计算照度平均值 a:rX9-**  
    9. 返回数据到FRED中 Kx`/\u=/
