    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。 (3h*sd5ly  
    QL2y,?Mz7  
    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: ])L'Rk#4  
    enableservice('AutomationServer', true) 5)7mjyo%  
    enableservice('AutomationServer') ewG21 q$  
    c.Y8CD.tqL  
    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 Q/n.T0Z ^

    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: 5#)<rK  
    1. 在FRED脚本编辑界面找到参考. zjS:;!8em  
    2. 找到Matlab Automation Server Type Library RM1uYFs<  
    3. 将名字改为MLAPP grdyiBSVn

    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。 vx@p;1RU`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: g <4M!gi  
    1. 创建Matlab服务器。 $F7gH  
    2. 移动探测面对于前一聚焦面的位置。 /VO@>Hoh  
    3. 在探测面追迹光线 '?gI cWM  
    4. 在探测面计算照度 [0ffOTy  
    5. 使用PutWorkspaceData发送照度数据到Matlab ].P(/~FS9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 h&M RQno  
    7. 用Matlab画出照度数据 _ 1> 4Q%  
    8. 在Matlab计算照度平均值 5b`xN!c  
    9. 返回数据到FRED中 !TL}~D:J
