    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。 gm8FmjZtf  
    Cs2F/M'  
    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: Gnthz0\]{  
    enableservice('AutomationServer', true) huat,zLS  
    enableservice('AutomationServer') k.n-JS  
    }K.2  
    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 }7HR<%< 7

    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: DG-XX.:z  
    1. 在FRED脚本编辑界面找到参考. dX;Q\  ]"  
    2. 找到Matlab Automation Server Type Library *Dhy a g  
    3. 将名字改为MLAPP &;2@*#,  
    X/qLg+X

    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。 ($T"m-e

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *l.tsICmbP  
    1. 创建Matlab服务器。 [bh8Nj\E  
    2. 移动探测面对于前一聚焦面的位置。 G ~X93J  
    3. 在探测面追迹光线 L ]Y6/Q   
    4. 在探测面计算照度 SL$ bV2T  
    5. 使用PutWorkspaceData发送照度数据到Matlab CzfGb4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9#MY(Hr  
    7. 用Matlab画出照度数据 oYR OGU  
    8. 在Matlab计算照度平均值 /'QfLW>6  
    9. 返回数据到FRED中 9g~"Y[ ]
