    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。 1`1U'ibhe  
    8r@_b  
    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: >5Vv6_CI0?  
    enableservice('AutomationServer', true) 7~@q#]U[  
    enableservice('AutomationServer') d` > '<  
    yyZV/ 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 3DH} YAUU

    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: OZ2gIK  
    1. 在FRED脚本编辑界面找到参考. m Cvgs  
    2. 找到Matlab Automation Server Type Library -nP y?>p"|  
    3. 将名字改为MLAPP }^).Y7{g[  
    M*|,05>  
    G]Fp},  
    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。 Ogp Zwwk

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1-`Il]@?8  
    1. 创建Matlab服务器。 2l5>>yY  
    2. 移动探测面对于前一聚焦面的位置。 E/MD]ox  
    3. 在探测面追迹光线 ?kfLOJQ:I  
    4. 在探测面计算照度 Gh3b*O_,  
    5. 使用PutWorkspaceData发送照度数据到Matlab j2A Z.s  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ttlFb]zZh  
    7. 用Matlab画出照度数据 +C4UM9  
    8. 在Matlab计算照度平均值 #*QnO\.  
    9. 返回数据到FRED中 X 4\
