    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。 ;@FCa j&  
    HD YWDp  
    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: x+8%4]u`  
    enableservice('AutomationServer', true) Mc9JFzp  
    enableservice('AutomationServer') <f9a%`d  
    NA!?.zn  
    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 c\le8C3  
    +'0V6 \y  
    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: 7ND4Booul  
    1. 在FRED脚本编辑界面找到参考. re)7h$f}  
    2. 找到Matlab Automation Server Type Library V.-cm51I  
    3. 将名字改为MLAPP Gq]/6igzX  
    U62Z ?nge%  
    5q;c=oRUj  
    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。 -x VZm8y

    4. 在探测面计算照度 (_3QZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab mEg3.|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 eX$RD9 H  
    7. 用Matlab画出照度数据 :{s0tw>Z
