    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。 ,SEC~)L  
    J LOTl.  
    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:  XL@Y!  
    enableservice('AutomationServer', true) |Ld/{&Qr  
    enableservice('AutomationServer') "6.JpUf  
    :4o08M%  
    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 KIt:ytFx  
    @S#>:o|  
    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: v0pyyUqS  
    1. 在FRED脚本编辑界面找到参考. !@ERAPuk  
    2. 找到Matlab Automation Server Type Library f<!3vAh  
    3. 将名字改为MLAPP g? 7%

    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。 HS1Gy/6'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: YS$?Wz  
    1. 创建Matlab服务器。 :H}a/ x*ur

    3. 在探测面追迹光线 +APf[ZpU  
    4. 在探测面计算照度 &[]0yNG  
    5. 使用PutWorkspaceData发送照度数据到Matlab dWC[p  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 R-v99e iN  
    7. 用Matlab画出照度数据 &r0b~RwUv  
    8. 在Matlab计算照度平均值 PFP/Pe Ng;  
    9. 返回数据到FRED中 Ift @/A
