    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。 L$}'6y/@  
    !)uXCg9U  
    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: C] |m|`  
    enableservice('AutomationServer', true) 5K|s]Y;  
    enableservice('AutomationServer') Oz.Zxw  
    'h{DjNSM  
    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 #M8>)oc

    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: O9)k)A]`O  
    1. 在FRED脚本编辑界面找到参考. aGmbB7[BZ  
    2. 找到Matlab Automation Server Type Library i-&"1D[&  
    3. 将名字改为MLAPP "'6R|<u=:

    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。 W7 9.,#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K#plSD^f=  
    1. 创建Matlab服务器。 @#| R{5=+  
    2. 移动探测面对于前一聚焦面的位置。 IV$2`)[A&X  
    3. 在探测面追迹光线 OY(znVHU  
    4. 在探测面计算照度 n`7n5M*  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7>|p_ o`e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u5dyhx7  
    7. 用Matlab画出照度数据 IR*:i{  
    8. 在Matlab计算照度平均值 \ffU15@N  
    9. 返回数据到FRED中 }i2dXC/
