    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^ )\  
    Nf5zQ@o_y  
    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: w#d7  
    enableservice('AutomationServer', true) 9oj#5Hq  
    enableservice('AutomationServer') N,bH@Q.Ci  
    >6KwZr BB  
    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 Dz3~cuVb

    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: YB+My~fw{l  
    1. 在FRED脚本编辑界面找到参考. *ZkOZ  
    2. 找到Matlab Automation Server Type Library 6vfut$)[{  
    3. 将名字改为MLAPP /B 53Z[yL

    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。 Q<Q?#v7NX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *DgRF/S  
    1. 创建Matlab服务器。 3o2x&v  
    2. 移动探测面对于前一聚焦面的位置。 >:bXw#w]  
    3. 在探测面追迹光线 =B{B ?B"r  
    4. 在探测面计算照度 Ofc u4pi  
    5. 使用PutWorkspaceData发送照度数据到Matlab w5+(A_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *x/H   
    7. 用Matlab画出照度数据 (GoxiX l  
    8. 在Matlab计算照度平均值 yRivf.wH  
    9. 返回数据到FRED中 ~}_S]^br
