    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。 tK0?9M.)  
    KxqJlben  
    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: r6JdF!\d  
    enableservice('AutomationServer', true) %i$]S`A}  
    enableservice('AutomationServer') e0qU2  
    # sm>;+J  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 r,aV11{  
    .r$d 8J  
    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: SCZtHEl9  
    1. 在FRED脚本编辑界面找到参考. qE!.C}L +  
    2. 找到Matlab Automation Server Type Library ^pIT,|myY7  
    3. 将名字改为MLAPP @LqLtr@A  
    "'~55bG  
    hv2@}<r?  
    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。 : OQx;>'

    6. 使用PutFullMatrix发送标量场数据到Matlab中 G&y< lh  
    7. 用Matlab画出照度数据 My vp PW
