    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。 |t~*!0>3  
    kS4YxtvB  
    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: t==\D?Rt  
    enableservice('AutomationServer', true) 5 zz">-Q !  
        enableservice('AutomationServer') 1Gy [^  
    U|Uc|6  
    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 a SMoee@!  
    &WZ&Tt/)/  
    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: CU:HTz=  
    1. 在FRED脚本编辑界面找到参考. S$ k=70H  
    2. 找到Matlab Automation Server Type Library j/;wxKW  
        3. 将名字改为MLAPP MlR ]+]  
         J,J6bfR/  
         {DZ xK(  
    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。 9"zp>VR

    现在将脚本代码公布如下,此脚本执行如下几个步骤: l{*Ko~g  
    1. 创建Matlab服务器。 0Oa&vx  
    2. 移动探测面对于前一聚焦面的位置。 kH`?^ ^_yJ  
    3. 在探测面追迹光线 *fz#B/ _o  
    4. 在探测面计算照度 Yl =-j  
    5. 使用PutWorkspaceData发送照度数据到Matlab R '8S)'l  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 yMt:L)+  
    7. 用Matlab画出照度数据 TfHL'u9B  
    8. 在Matlab计算照度平均值 ^^F 8M0k3  
    9. 返回数据到FRED中 frc9
