    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。 VG>vn`x>a  
    kZ=s'QRgL  
    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: g%k`  
    enableservice('AutomationServer', true) c1xrn4f@a  
    enableservice('AutomationServer') . ]8E7  
    wlPx,UqZ  
    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 u@3y&b  
    dCFlM&(i  
    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: $ F S_E  
    1. 在FRED脚本编辑界面找到参考. {bPV)RL:  
    2. 找到Matlab Automation Server Type Library z~\t|Z]G,|  
    3. 将名字改为MLAPP Ou>vX[{  
    BJS-Jy$-  
    lW 81q2n  
    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。 wap3Kd>MP

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Gc$gJnQio  
    1. 创建Matlab服务器。 g_Im;1$  
    2. 移动探测面对于前一聚焦面的位置。 -TV?E%r  
    3. 在探测面追迹光线 S:61vD  
    4. 在探测面计算照度 Oi} T2I  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7_# 1Ec|;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 BtY%r7^o  
    7. 用Matlab画出照度数据 tW;:-  
    8. 在Matlab计算照度平均值 **>/}.%?K  
    9. 返回数据到FRED中 #pHs@uvO
