    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.dr<  
    r6nnRN/S=  
    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: OIJT~Z}  
    enableservice('AutomationServer', true) KZTLIZxI-  
    enableservice('AutomationServer') #N"u 0  
    tS>^x  
    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 1yZA_x15:  
    ="5D}%  
    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: <:Mz2Rg  
    1. 在FRED脚本编辑界面找到参考. $C sE[+k1  
    2. 找到Matlab Automation Server Type Library O5aXa_A_u  
    3. 将名字改为MLAPP ] j8bv3  
    yx|{:Li!  
    i!RfUod  
    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。 7FJ4;HLQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h=0a9vIXF  
    1. 创建Matlab服务器。 A .Wf6o  
    2. 移动探测面对于前一聚焦面的位置。 !\<a2>4$T  
    3. 在探测面追迹光线 hPUAm6 b;  
    4. 在探测面计算照度 9=~ZA{0J  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1f<R,>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 e6>G8d  
    7. 用Matlab画出照度数据 ) $_1U!z  
    8. 在Matlab计算照度平均值 MqB@}!  
    9. 返回数据到FRED中 W;yc)JB
