    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。 .<gA a"  
    Z`o}xV  
    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: k+ 5:fB)z  
    enableservice('AutomationServer', true) ~=aGv%vX  
    enableservice('AutomationServer') KVvIo1$N  
    ]t\fw'  
    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 wWko9h=|mQ  
    `E8m> q Ss  
    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: Z=|:D,&  
    1. 在FRED脚本编辑界面找到参考. ~!E% GCyFy  
    2. 找到Matlab Automation Server Type Library vE;`y46&r  
    3. 将名字改为MLAPP UN'hnqC

    'M=(5p  
    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。 kn 5q1^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |fYNkD 8z1  
    1. 创建Matlab服务器。 57Y(_h:  
    2. 移动探测面对于前一聚焦面的位置。 Se9I1~mX  
    3. 在探测面追迹光线 cR 4xy26s  
    4. 在探测面计算照度 _*0!6?c  
    5. 使用PutWorkspaceData发送照度数据到Matlab <:-|>R".  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]7^OTrZ N  
    7. 用Matlab画出照度数据 M}!7/8HUC  
    8. 在Matlab计算照度平均值 $2A%y14  
    9. 返回数据到FRED中 1`Cr1pH
