    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。 Xv!Gg6v6  
    `W)?d I?#M  
    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: LhAW|];  
    enableservice('AutomationServer', true) y ]@JkF(  
    enableservice('AutomationServer') *Xk5H,:  
    }gX hN"  
    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 sHBTB6)lx

    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: 3)W_^6>bM  
    1. 在FRED脚本编辑界面找到参考. V^Z5i]zT  
    2. 找到Matlab Automation Server Type Library !~?/D  
    3. 将名字改为MLAPP C=&n1/

    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。 Ip7#${f5M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /Lr`Aka5  
    1. 创建Matlab服务器。 <v -YMk@  
    2. 移动探测面对于前一聚焦面的位置。 ZlC+DXg#S  
    3. 在探测面追迹光线 8 f~x\.  
    4. 在探测面计算照度 L%$ -?O|  
    5. 使用PutWorkspaceData发送照度数据到Matlab B`R@%US  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]3,9 ."^  
    7. 用Matlab画出照度数据 @R`6j S_gK  
    8. 在Matlab计算照度平均值 Ua|iAD 1  
    9. 返回数据到FRED中 .+XK>jl +
