    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。 =hMY2D  
    qIAoA .  
    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: n;:rf7hGY  
    enableservice('AutomationServer', true) dtc IC0:[  
    enableservice('AutomationServer') /\W Qx e  
    U~ck!\0&T  
    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 7Ddaf>

    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: 1Q. \s_2  
    1. 在FRED脚本编辑界面找到参考. :M6+p'`j  
    2. 找到Matlab Automation Server Type Library n8D xB@DI  
    3. 将名字改为MLAPP $.[#0lCI

    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。 =F;.l@:

    1. 创建Matlab服务器。 m:/ wG& !  
    2. 移动探测面对于前一聚焦面的位置。 ,Uy|5zv  
    3. 在探测面追迹光线 PfZ+PqS  
    4. 在探测面计算照度 91xB9k1zO  
    5. 使用PutWorkspaceData发送照度数据到Matlab <&:=z?30"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4~N[%>zJ  
    7. 用Matlab画出照度数据 -G|G_$9
