    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。 }5tn  
    0RSa{iS*A  
    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: C aJD*  
    enableservice('AutomationServer', true) /l$noaskX  
    enableservice('AutomationServer') xf]4!zE  
    -X}R(.}x  
    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 wbS++cF<  
    ^&rb I,D  
    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: &s<  
    1. 在FRED脚本编辑界面找到参考. Csc2yI%3  
    2. 找到Matlab Automation Server Type Library ,6buo~?W:  
    3. 将名字改为MLAPP N8{>M,  
    e#OU {2X  
    +Ae.>%}  
    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。 sk3 ;;<H

    1. 创建Matlab服务器。 B&$89]gs|  
    2. 移动探测面对于前一聚焦面的位置。 8Z!ea3kAT  
    3. 在探测面追迹光线 _/=ZkI5  
    4. 在探测面计算照度 2Ls<OO  
    5. 使用PutWorkspaceData发送照度数据到Matlab PYf`a`dH  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )yK!qu  
    7. 用Matlab画出照度数据 -?'CUm*Od  
    8. 在Matlab计算照度平均值 g:clSN,
