    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。 I 2OQ  
    $$o(  
    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: f##/-NG  
    enableservice('AutomationServer', true) oyk&]'>  
    enableservice('AutomationServer') vV 9vB3K5?  
    T2azHo7  
    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 QZ;DZMP  
    <~w3[i=  
    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: ]e"!ZR?XJ  
    1. 在FRED脚本编辑界面找到参考. X2% (=B  
    2. 找到Matlab Automation Server Type Library srO>l ;Vf/  
    3. 将名字改为MLAPP #Y

    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。 mDbTOtD

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8{i}^.p  
    1. 创建Matlab服务器。 4~FRE)8  
    2. 移动探测面对于前一聚焦面的位置。 0pEM0M  
    3. 在探测面追迹光线 4L{]!dox  
    4. 在探测面计算照度 S|LY U!IWZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1t?OD_d!8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 whHuV*K}  
    7. 用Matlab画出照度数据 F?H=2mzKbz  
    8. 在Matlab计算照度平均值 E7@Gpu,o  
    9. 返回数据到FRED中 k[a<KbS
