    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。 6F_:,b^  
    pnTz.)'46  
    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: 1T}jK^"  
    enableservice('AutomationServer', true) wlFK#iK  
        enableservice('AutomationServer') CI1K:K AM  
    ;]l`Q,*OXb  
    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 ~NTKWRaR  
    YQ>O6:%  
    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: 73l,PJ  
    1. 在FRED脚本编辑界面找到参考. uN=f( -"  
    2. 找到Matlab Automation Server Type Library a Z8f>t1Q  
        3. 将名字改为MLAPP y9U~4  
         `$MO;Fv,G  
         }yaM.+8.  
    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。 XZ<8M}Lg

    1. 创建Matlab服务器。 7AF6aog  
    2. 移动探测面对于前一聚焦面的位置。 deEc;IAo  
    3. 在探测面追迹光线 \A6 }=  
    4. 在探测面计算照度 !p Q*m`Xo  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,0eXg  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 kDG?/j90D  
    7. 用Matlab画出照度数据 OBf$Z"i  
    8. 在Matlab计算照度平均值 R5xV_;wD  
    9. 返回数据到FRED中 '$[a-)4
