    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。 k{^iv:  
    +n|@'= ]  
    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: R ~#&xfMd.  
    enableservice('AutomationServer', true) !1bATO:x  
        enableservice('AutomationServer') W{kTM4  
    9['>$ON  
    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 y*I,i*iv  
    Lcs?2c:%  
    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: IXR%IggJA  
    1. 在FRED脚本编辑界面找到参考. z*N%kcw"  
    2. 找到Matlab Automation Server Type Library h-*h;Uyc  
        3. 将名字改为MLAPP F[0w*i&u5  
         OX.g~M ig|  
         F=;nWQ&  
    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。 v=YI%{tx)

    1. 创建Matlab服务器。 |eej}G(,m}  
    2. 移动探测面对于前一聚焦面的位置。 j<A; i  
    3. 在探测面追迹光线 0}$R4<"{Y>  
    4. 在探测面计算照度 +Ui%}^ZZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5>h# hcL  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 %nj{eT  
    7. 用Matlab画出照度数据 F\+!\b*lP  
    8. 在Matlab计算照度平均值 ER<Z!*2  
    9. 返回数据到FRED中 [} "m4+
