    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。 sJ]taY ou  
    ^5=B`aich  
    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: 44-R!  
    enableservice('AutomationServer', true) dDF .qXq.  
    enableservice('AutomationServer') W3iZ|[E;  
    OK\A</8r  
    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 `X3^fg  
    gdkwWoN .  
    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: =2@B&  
    1. 在FRED脚本编辑界面找到参考. Vb9',a?#n  
    2. 找到Matlab Automation Server Type Library 1&e} ms  
    3. 将名字改为MLAPP kYLM&&h

    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。 y~75r\"R

    现在将脚本代码公布如下,此脚本执行如下几个步骤: lGVEpCS}  
    1. 创建Matlab服务器。 4fe7U=#;Y  
    2. 移动探测面对于前一聚焦面的位置。 3;a<_cE*@  
    3. 在探测面追迹光线 $ aUo aI  
    4. 在探测面计算照度 EOm:!D\  
    5. 使用PutWorkspaceData发送照度数据到Matlab hcyM6:}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7e<c$t#H  
    7. 用Matlab画出照度数据 mW:!M!kk  
    8. 在Matlab计算照度平均值 z`\F@pX%wC  
    9. 返回数据到FRED中 x:QgjK
