    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。 e+WVN5"ID>  
    u^uG_^^,/  
    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: ]z%9Q8q'  
    enableservice('AutomationServer', true) TDGzXJf[  
    enableservice('AutomationServer') ?yb{DZ46  
    5~F0'tb|}  
    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 OR9){qP  
    F"C Yrt  
    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: A~>=l=  
    1. 在FRED脚本编辑界面找到参考. `QF|> N  
    2. 找到Matlab Automation Server Type Library E=QQZ\w  
    3. 将名字改为MLAPP 'W*F[U*&HP  
    zE/(F;> FV  
    mTgn}rXk  
    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。 B=r/(e

    现在将脚本代码公布如下,此脚本执行如下几个步骤: yw<xv-Q=i  
    1. 创建Matlab服务器。 k#&SWp=

    3. 在探测面追迹光线 ( -@>  
    4. 在探测面计算照度 J5T#}!f  
    5. 使用PutWorkspaceData发送照度数据到Matlab AlxS?f2w  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {@%(0d{n}  
    7. 用Matlab画出照度数据 pAuwSn#i  
    8. 在Matlab计算照度平均值 ?OyW|jL  
    9. 返回数据到FRED中 TbVL71c
