    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。  hRqr  
    ^_BjO(b'e  
    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: 'f8'|o)  
    enableservice('AutomationServer', true) GE=PaYz  
    enableservice('AutomationServer') 2"WP>>b80  
    @Thrizh  
    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 lBudC  
    onm" 7JsO'  
    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: J|([(  
    1. 在FRED脚本编辑界面找到参考. TY?O$d2b3  
    2. 找到Matlab Automation Server Type Library #$l:%  
    3. 将名字改为MLAPP Hx n#vAc  
    Bve',.xH  
    AuY*x;~  
    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。 H#G3CD2&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &w:0ad|  
    1. 创建Matlab服务器。 <@c@`K  
    2. 移动探测面对于前一聚焦面的位置。 FytGg[#]  
    3. 在探测面追迹光线 \y+^r|IL  
    4. 在探测面计算照度 0 c ]]  
    5. 使用PutWorkspaceData发送照度数据到Matlab ULO_?4}B  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 AqH GBH0  
    7. 用Matlab画出照度数据 5x!rT&!G  
    8. 在Matlab计算照度平均值 uUe#+[bD  
    9. 返回数据到FRED中 G/_xn5XDD
