    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。 f^ q0#+k)  
    dMcCSwYh  
    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: sn|q EH  
    enableservice('AutomationServer', true) gH{X?  
        enableservice('AutomationServer')  zw13Tu  
    D4CN%^?  
    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 D)yCuw{M:  
    P>*g'OK^!G  
    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: q T16th[D  
    1. 在FRED脚本编辑界面找到参考. [31vx0$_p  
    2. 找到Matlab Automation Server Type Library m\3r<*q6  
        3. 将名字改为MLAPP {I/|7b>@r  
         4v@urW s  
         8{mQmG4  
    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。 yMdAe>@

    3. 在探测面追迹光线 P)7_RE*gY  
    4. 在探测面计算照度 XM0;cF

        6. 使用PutFullMatrix发送标量场数据到Matlab中 IEi E6z]L(  
    7. 用Matlab画出照度数据 ?q}XD c
