    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。 !'scOWWn  
    =)QtE|p,77  
    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:  =ie8{j2:  
    enableservice('AutomationServer', true) \A "_|Yg  
    enableservice('AutomationServer') z 3((L  
    WRIOjQ:  
    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 P5;n(E(19

    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+3ico]f@  
    1. 在FRED脚本编辑界面找到参考. !'m MGxkEb  
    2. 找到Matlab Automation Server Type Library LelCjC{`1  
    3. 将名字改为MLAPP =T7lv%u  
    y-C=_v_X  
    xwvg @  
    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。 Yvmo%.oU

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Hg[g{A_G[  
    1. 创建Matlab服务器。 JdYmUM|K/c  
    2. 移动探测面对于前一聚焦面的位置。 .0ov>4,R  
    3. 在探测面追迹光线 ,^Ug[pGG-  
    4. 在探测面计算照度 4S9hz  
    5. 使用PutWorkspaceData发送照度数据到Matlab o4Ny9s  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "p Rr>Fa  
    7. 用Matlab画出照度数据 "Sx}7?8AB  
    8. 在Matlab计算照度平均值 (g(.gN]  
    9. 返回数据到FRED中 EuH[G_5e0
