    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。 nP3  E  
    +ulagE|7  
    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: $B (kZ  
    enableservice('AutomationServer', true) O_~7Glu  
    enableservice('AutomationServer') [}z,J"Un  
    /=:j9FF  
    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 `]i []|

    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: p3(2?UO!  
    1. 在FRED脚本编辑界面找到参考. F@YKFk+a  
    2. 找到Matlab Automation Server Type Library "i^ GmVn

    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。 ";SiL{Z

    3. 在探测面追迹光线 (p#0)C  
    4. 在探测面计算照度 pCi#9=?N

    6. 使用PutFullMatrix发送标量场数据到Matlab中 p>w]rE:}
