    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。 CYTuj>Ww  
    O]$*EiO\  
    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: ^5FJ}MMJf  
    enableservice('AutomationServer', true) (7rz:  
    enableservice('AutomationServer') TNX%_Q<  
    +7lRP)1R  
    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 Z,N7nMJf  
    n!CP_  
    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|R3,<Q]  
    1. 在FRED脚本编辑界面找到参考. K 8yyxJ  
    2. 找到Matlab Automation Server Type Library A^= Hu,"e  
    3. 将名字改为MLAPP mhJOR'2

    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。 l b1sV

    5. 使用PutWorkspaceData发送照度数据到Matlab %;B(_ht<-w  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 I}g|n0o
