    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。 M@.S Q@E  
    T3z ovnR  
    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: x5Lbe5/P  
    enableservice('AutomationServer', true) 3Vc}Q'&Y  
    enableservice('AutomationServer') ~?ezd0  
    6(`N!]e*L  
    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 8eS(gKD  
    )dhR&@r*w  
    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: Qs,\P^n  
    1. 在FRED脚本编辑界面找到参考. hXjZ>n``  
    2. 找到Matlab Automation Server Type Library *{w0=J[15  
    3. 将名字改为MLAPP -|m3=#  
    +112{v=!i  
    '37 {$VHw  
    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。 Mc@9ivwL#

    2. 移动探测面对于前一聚焦面的位置。 jDY B*Y^F  
    3. 在探测面追迹光线 U~: H>  
    4. 在探测面计算照度 1PwtzH .w  
    5. 使用PutWorkspaceData发送照度数据到Matlab b}R_@_<u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 s0?'mC+p  
    7. 用Matlab画出照度数据 DPzW,aIgv  
    8. 在Matlab计算照度平均值 r V%6 8x9  
    9. 返回数据到FRED中 C{J5:ak
