    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。 {]T?)!V m  
    B.q/}\ ?(  
    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: hIJtu;}zU  
    enableservice('AutomationServer', true) zt(lV  
    enableservice('AutomationServer') /;*_[g5*i  
    y|5L%,i  
    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 51jgx,-|$  
    ^+_rv  
    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: ,vR?iNd:q[  
    1. 在FRED脚本编辑界面找到参考. K~TwyB-h  
    2. 找到Matlab Automation Server Type Library !D#"+&&G8  
    3. 将名字改为MLAPP h_%q`y,  
    1M]=Nv  
    SYCL\b   
    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。 y[8;mCh

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 7D6`1 &  
    1. 创建Matlab服务器。 K^u,B3  
    2. 移动探测面对于前一聚焦面的位置。 K-0=#6?y4  
    3. 在探测面追迹光线 u 272)@R  
    4. 在探测面计算照度 !g@K y$  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7Sx|n}a-3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Jo5Bmh0  
    7. 用Matlab画出照度数据 !5`MiH  
    8. 在Matlab计算照度平均值 h  d3  
    9. 返回数据到FRED中 v(1 [n]y
