    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。 -1g :3'% P  
    G21o @38e  
    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: az(<<2=  
    enableservice('AutomationServer', true) FM@iIlY"  
    enableservice('AutomationServer') Ic#xz;elM  
    *glZb;_  
    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 18>cfDh;N

    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: n{ ;j  
    1. 在FRED脚本编辑界面找到参考. W_\zx<m  
    2. 找到Matlab Automation Server Type Library _/s"VYFZ  
    3. 将名字改为MLAPP /~[Lr

    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。 IU%|K~_n

    1. 创建Matlab服务器。 11[lc2  
    2. 移动探测面对于前一聚焦面的位置。 $cCC 1=dW  
    3. 在探测面追迹光线 \*xB<mq  
    4. 在探测面计算照度 ~U9K<_U  
    5. 使用PutWorkspaceData发送照度数据到Matlab &XP(D5lf`B  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -u2i"I730  
    7. 用Matlab画出照度数据 |\5^ub,m  
    8. 在Matlab计算照度平均值 G6sK3K  
    9. 返回数据到FRED中 `Lf'/q
