    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。 rw ^^12)  
    !MTm4Ls  
    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: x*}(l%[  
    enableservice('AutomationServer', true) 6i9m!YQV  
    enableservice('AutomationServer') s,]6Lri`\  
    P`-(08t  
    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 HqcXP2  
    cd) <t8^KE  
    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: ]m=* =LLC  
    1. 在FRED脚本编辑界面找到参考. O)\xElu  
    2. 找到Matlab Automation Server Type Library P2 !~}{-  
    3. 将名字改为MLAPP 7EI(7:gOn  
    4AZlr*U  
    !}l)okQH<#  
    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。 P-7!\[];te

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K)_0ej~C  
    1. 创建Matlab服务器。 H1s{JJAM>i  
    2. 移动探测面对于前一聚焦面的位置。 `axNeqM  
    3. 在探测面追迹光线 N95"dNZE  
    4. 在探测面计算照度 rZKv:x}{6  
    5. 使用PutWorkspaceData发送照度数据到Matlab I@pnZ-5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7M3q|7 ?  
    7. 用Matlab画出照度数据 jdXkU  
    8. 在Matlab计算照度平均值 .NQoqXR  
    9. 返回数据到FRED中 rYJt;/RtR}
