    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。 C:EoUu  
    5|t&qUV  
    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: z2zp c^i  
    enableservice('AutomationServer', true) qr;" K?NX  
    enableservice('AutomationServer') *,*5sV  
    xEWa<P#.u  
    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 LMzYsXG*[

    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: 6FFv+{ 2^@  
    1. 在FRED脚本编辑界面找到参考. NdQ?3'WJ  
    2. 找到Matlab Automation Server Type Library | lfPd  
    3. 将名字改为MLAPP G ~\$Oq8  
    'Em($A (  
    },ZL8l{  
    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。 NVPYv#uK

    1. 创建Matlab服务器。 @"2-tn@q_

    3. 在探测面追迹光线 1'B?f# s  
    4. 在探测面计算照度 86VuPV-

    6. 使用PutFullMatrix发送标量场数据到Matlab中 Nh-* Gt?  
    7. 用Matlab画出照度数据 O$^YUHD
