    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。 y7: tr  
    P`S@n/}  
    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: 2C$R4:Ssw)  
    enableservice('AutomationServer', true) Ts9ktPlm  
        enableservice('AutomationServer') =bLY /  
    o%`Xa#*Ly  
    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 nPN?kO=]

    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: "0CjP+1k  
    1. 在FRED脚本编辑界面找到参考. O/Rhf[7v*  
    2. 找到Matlab Automation Server Type Library ujr(K=E  
        3. 将名字改为MLAPP tnz+bX26  
         h1[WhBL-O  
         cK@jmGj+  
    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。 c>HK9z{

    3. 在探测面追迹光线 5GQLd  
    4. 在探测面计算照度 )JD(`

        6. 使用PutFullMatrix发送标量场数据到Matlab中 F%d \~Vj  
    7. 用Matlab画出照度数据 uH@FU60
