    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。 PizPsJ|&  
    Me*]Bh  
    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: r5?qz<WW~  
    enableservice('AutomationServer', true) !23#Bz7  
    enableservice('AutomationServer') )TcW.d6  
    !M&B=vk4  
    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 #nh;KlI 0

    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: sj@'C@oK  
    1. 在FRED脚本编辑界面找到参考. L$+ap~ld  
    2. 找到Matlab Automation Server Type Library BqKh&m  
    3. 将名字改为MLAPP _,4f z(  
    l0$ +)FKd

    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。 S)*eAON9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Q04iuhDO:  
    1. 创建Matlab服务器。 k w!1]N  
    2. 移动探测面对于前一聚焦面的位置。 nNFZ77lg  
    3. 在探测面追迹光线 $u9y H Z  
    4. 在探测面计算照度 rX#} 2  
    5. 使用PutWorkspaceData发送照度数据到Matlab cwxO| .m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 HJ*W3Mg  
    7. 用Matlab画出照度数据 ~WJEH#
