    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。 k ucbI_  
    ECOJ .^  
    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: (-gomn  
    enableservice('AutomationServer', true) LqbI/AQ)  
    enableservice('AutomationServer') 5EFt0?G   
    oZa'cZNs  
    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 lS4rpbU_

    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: 4.!1odKp  
    1. 在FRED脚本编辑界面找到参考. jVQy{8{G  
    2. 找到Matlab Automation Server Type Library VBX)xQazU  
    3. 将名字改为MLAPP W:_-I4 q~  
    e9o\qEm   
    cLV*5?gVO  
    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。 k7^hc th

    4. 在探测面计算照度 8K,X3a9

    6. 使用PutFullMatrix发送标量场数据到Matlab中 \N9=13W<lK
