    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。 Vx4pP$S  
    Jm1AJ4mw  
    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: -mYI[AG)  
    enableservice('AutomationServer', true) XJ1nhE  
        enableservice('AutomationServer') 4.kkxQR7r  
    s8I77._s  
    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 !=Vh2UbC3  
    w!h{P38  
    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: 3SB7)8Id1  
    1. 在FRED脚本编辑界面找到参考. cZK?kz_Y  
    2. 找到Matlab Automation Server Type Library S0QU@e  
        3. 将名字改为MLAPP T+{'W  
         XxU}|jTO#  
         89e.\EH  
    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。 SD.*G'N&2f

    2. 移动探测面对于前一聚焦面的位置。 XV9'[V  
    3. 在探测面追迹光线 eOmxA<h  
    4. 在探测面计算照度 7Sv5fLu2  
    5. 使用PutWorkspaceData发送照度数据到Matlab x=r6vOj  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ?lna8]t  
    7. 用Matlab画出照度数据 !-o||rt  
    8. 在Matlab计算照度平均值 =,;3z/k%  
    9. 返回数据到FRED中 9- <V%eNX
