    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。 .!ThqYo  
    '1lr "}"Q+  
    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: =#@eDm%  
    enableservice('AutomationServer', true) 'E2\e!U/  
    enableservice('AutomationServer') } PD]e*z{Z  
    mJ=3faM  
    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 o#KGENd

    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: 289@O-  
    1. 在FRED脚本编辑界面找到参考. )P:r;a'  
    2. 找到Matlab Automation Server Type Library ~+1t3M e  
    3. 将名字改为MLAPP $]4>;gTL'

    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。 ^goa$ uxU

    现在将脚本代码公布如下,此脚本执行如下几个步骤: i5  x[1  
    1. 创建Matlab服务器。 cd36f26`"w  
    2. 移动探测面对于前一聚焦面的位置。 <}~`YU>=v  
    3. 在探测面追迹光线 ]Mu + DZ  
    4. 在探测面计算照度 \\80c65-  
    5. 使用PutWorkspaceData发送照度数据到Matlab l0Myem v?z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B3V:?#  
    7. 用Matlab画出照度数据 DPuz'e*  
    8. 在Matlab计算照度平均值 vkdU6CZO  
    9. 返回数据到FRED中 t.sbfLu
