    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。 IwOfZuS  
    01'y^`\xQ  
    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: "Fo  
    enableservice('AutomationServer', true) ]Pz|Oi+]  
    enableservice('AutomationServer') e_tZja2s  
    $HP/c Ku  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 9$n+-GSK

    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: `e4o1 *  
    1. 在FRED脚本编辑界面找到参考. -wJ   
    2. 找到Matlab Automation Server Type Library 6oPUYn-  
    3. 将名字改为MLAPP /vMQF+  
    Cln^1N0  
    `" i^'VL,  
    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。 j0Id!o

    现在将脚本代码公布如下,此脚本执行如下几个步骤: SjFF=ib  
    1. 创建Matlab服务器。 nYmf(DV  
    2. 移动探测面对于前一聚焦面的位置。 MHC.k=  
    3. 在探测面追迹光线 8ct+?-3g  
    4. 在探测面计算照度 \H},ou U  
    5. 使用PutWorkspaceData发送照度数据到Matlab d<e+__ 2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 z7D*z8,i  
    7. 用Matlab画出照度数据 .~FKyP>[$  
    8. 在Matlab计算照度平均值 `two|gX0K  
    9. 返回数据到FRED中 qiF@7i
