    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。 ~"dA~[r L  
    *v?`<)P#  
    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: U T>s 5C  
    enableservice('AutomationServer', true) X#d~zk[r2  
        enableservice('AutomationServer') 5&xB6|k  
    )js)2L~  
    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 -VZ-<\uH

    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: S(QpM.9*  
    1. 在FRED脚本编辑界面找到参考. z,|r*\dw  
    2. 找到Matlab Automation Server Type Library YgKZ#?*  
        3. 将名字改为MLAPP YpQ7)_s ?

    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。 M=.:,wRm

    3. 在探测面追迹光线 -7m:91x  
    4. 在探测面计算照度 INUG*JC6  
    5. 使用PutWorkspaceData发送照度数据到Matlab [N1hWcfvd  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 J~=n`pW  
    7. 用Matlab画出照度数据 |}2 3>l7
