    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。 &nYmVwi?"Q  
    )yk LUse+  
    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: UJI1n?~  
    enableservice('AutomationServer', true) :?TV6M  
    enableservice('AutomationServer') ~zx-'sc?  
    FP$]D~DMo  
    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 qJ !xhf1  
    i || /=ai  
    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: ]pt @  
    1. 在FRED脚本编辑界面找到参考. Onl:eG;@  
    2. 找到Matlab Automation Server Type Library Q. >"@c[  
    3. 将名字改为MLAPP @S}'_g  
    'D bHXS7N  
    L2N/DB'{  
    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。 PHoW|K_e

    现在将脚本代码公布如下,此脚本执行如下几个步骤: f%af.cR*  
    1. 创建Matlab服务器。 3yQ(,k#  
    2. 移动探测面对于前一聚焦面的位置。 ,SBL~JJ  
    3. 在探测面追迹光线 0y(d|;':  
    4. 在探测面计算照度 {5*5tCIt  
    5. 使用PutWorkspaceData发送照度数据到Matlab k$zDofdfp  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ,70|I{,Km  
    7. 用Matlab画出照度数据 Y9C]-zEv  
    8. 在Matlab计算照度平均值 k~H-:@  
    9. 返回数据到FRED中 6 ^p 6v
