    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。 NYP3uGH]  
    MruWt*  
    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: Qlb@Az  
    enableservice('AutomationServer', true) "fpj"lf-  
    enableservice('AutomationServer') $elrX-(vL  
    HAO/r`7*  
    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 Ka_UVKwMro

    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: c6c^9*,V  
    1. 在FRED脚本编辑界面找到参考. +=k?Dp[  
    2. 找到Matlab Automation Server Type Library C9=f=sGL  
    3. 将名字改为MLAPP e<9nt [  
    m/eGnv;!

    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。 2M&4]d

    1. 创建Matlab服务器。 E<\\'VF  
    2. 移动探测面对于前一聚焦面的位置。 }qKeX4\-

    4. 在探测面计算照度 L//sJe  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9d{W/t?NH  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w4x8 Sre  
    7. 用Matlab画出照度数据  g u|;C  
    8. 在Matlab计算照度平均值 8W$="s2
