    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。 dY1t3@E  
    R"nB4R0Uh  
    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: IiYL2JS;t|  
    enableservice('AutomationServer', true) L}Z.FqJ  
    enableservice('AutomationServer') cO?*(e1m=  
    @Z5q2Q  
    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 +H-=`+,

    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: #6 M] tr  
    1. 在FRED脚本编辑界面找到参考. w\buQ6pR)  
    2. 找到Matlab Automation Server Type Library ,KY;NbL-Jp  
    3. 将名字改为MLAPP T7[@ lMa?

    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。 u0C:q`;z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8P n  
    1. 创建Matlab服务器。 +R'8$  
    2. 移动探测面对于前一聚焦面的位置。 Ob0sB@  
    3. 在探测面追迹光线 ]7HR U6$  
    4. 在探测面计算照度 UHl3/m7g  
    5. 使用PutWorkspaceData发送照度数据到Matlab {lI}a8DP  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ZrN(M p  
    7. 用Matlab画出照度数据 >"W^|2R  
    8. 在Matlab计算照度平均值 -E-#@s  
    9. 返回数据到FRED中 H%_^Gy8f
