    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。 h/~BUg'  
    FQRcZpv;  
    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. ?dI82c  
    enableservice('AutomationServer', true) Mp}NUQHE  
    enableservice('AutomationServer') \5c -L_  
    7n]%`Yb  
    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 6HQwL\r79  
    <G=@Gl  
    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: j@\/]oL^We  
    1. 在FRED脚本编辑界面找到参考. dp W%LXM_  
    2. 找到Matlab Automation Server Type Library vy y\^nL  
    3. 将名字改为MLAPP T1[ZrY'0

    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。 -\v8i.w0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: dR{ V,H7N  
    1. 创建Matlab服务器。 -{mq\GvGn  
    2. 移动探测面对于前一聚焦面的位置。 _ 9]3S>Rn  
    3. 在探测面追迹光线 5ml}TSMu'  
    4. 在探测面计算照度 l[{}ZKZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab u6d~d\  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4u7>NQUDu  
    7. 用Matlab画出照度数据 bd;f@)X  
    8. 在Matlab计算照度平均值 /hR]aw  
    9. 返回数据到FRED中 SXF_)1QO\W
