    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。 :kgwKuhL  
    p_[k^@ $  
    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: 'I;pS)sb  
    enableservice('AutomationServer', true) b+hZ<U/  
        enableservice('AutomationServer') ~fr1O`8  
    bvAO(`  
    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 wZ29/{,  
    Q7i^VN  
    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: eE1w<] Eg  
    1. 在FRED脚本编辑界面找到参考. eGZId v1  
    2. 找到Matlab Automation Server Type Library w)hJ0k  
        3. 将名字改为MLAPP P[^!Uq[0n7

         9erTb?@S  
    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。 #t9&X8:U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: F)!B%4  
    1. 创建Matlab服务器。 k4eV*e8  
    2. 移动探测面对于前一聚焦面的位置。 h}.0Ne  
    3. 在探测面追迹光线 b5KX`r  
    4. 在探测面计算照度 J1g `0XH  
    5. 使用PutWorkspaceData发送照度数据到Matlab i |cSO2O+  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 UtY< R  
    7. 用Matlab画出照度数据 ]l`?"X|^  
    8. 在Matlab计算照度平均值 3xbA]u;gp  
    9. 返回数据到FRED中 E}yl@8g:#
