    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。 va0{>Dc+  
    Y/*mUS[oa  
    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: rogT~G}q  
    enableservice('AutomationServer', true) qHrc9fB  
    enableservice('AutomationServer') tIuCct-  
    }n>p4W"OM  
    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 >7QvK3S4%

    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: t&AFU t\c  
    1. 在FRED脚本编辑界面找到参考. XMxSQ B1  
    2. 找到Matlab Automation Server Type Library sG92XJ  
    3. 将名字改为MLAPP ?M\{&mlF  
    ]d! UJ&<?  
    ;5659!;  
    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。 >LOjV0K/

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !1$])VQWI  
    1. 创建Matlab服务器。 e4>_v('  
    2. 移动探测面对于前一聚焦面的位置。 =4FXBPoQK  
    3. 在探测面追迹光线 0.8  2kl  
    4. 在探测面计算照度 V3^&oe%  
    5. 使用PutWorkspaceData发送照度数据到Matlab R}*_~7r5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +JjW_Rl?=V  
    7. 用Matlab画出照度数据 pHLB= r  
    8. 在Matlab计算照度平均值 lPw%ErG  
    9. 返回数据到FRED中 YS/Yd[ e
