    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。 > lg-j-pV  
    4gRt^T-?  
    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: gfW8s+  
    enableservice('AutomationServer', true) ,b/qcu_|-  
    enableservice('AutomationServer') A,4|UA?-  
    E)h&<{%  
    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 n,+/%IZ

    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: Rl2*oOVz  
    1. 在FRED脚本编辑界面找到参考. $%ts#56*  
    2. 找到Matlab Automation Server Type Library Vs0T*4C=n  
    3. 将名字改为MLAPP j>KJgSs]&\

    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。 J4 Tc q

    3. 在探测面追迹光线 (6*CORE   
    4. 在探测面计算照度 ygA~d9"  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9ne13 qVm+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 O DLRzk(  
    7. 用Matlab画出照度数据  3~mi
