    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。 +):t6oX|  
    im&E \`L7  
    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: h+mM  
    enableservice('AutomationServer', true) Sd;/yC8  
        enableservice('AutomationServer') &tFVW[(  
    X!5  
    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 }?,Gn]]

    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: 8?S32Gdu  
    1. 在FRED脚本编辑界面找到参考. :$&%Pxm  
    2. 找到Matlab Automation Server Type Library qC9$xIWq  
        3. 将名字改为MLAPP 'hl>pso.

    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。 OE(H:^ZR

    2. 移动探测面对于前一聚焦面的位置。 zdCeOZ 6  
    3. 在探测面追迹光线 ! /Z{uy  
    4. 在探测面计算照度 -If-c'"G  
    5. 使用PutWorkspaceData发送照度数据到Matlab @ViJJ\  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 .BGM1ph}~  
    7. 用Matlab画出照度数据 ./@!k[
