    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。 r"{<%e  
    ..W-76{  
    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: _. V?A*  
    enableservice('AutomationServer', true) aM=D84@  
    enableservice('AutomationServer') 9X}I>  
    jO~:<y3 =  
    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 (Ddp|a"b  
    {b)~V3rsY  
    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: LnsD  
    1. 在FRED脚本编辑界面找到参考. )?aaBaN$  
    2. 找到Matlab Automation Server Type Library g"_C,XN  
    3. 将名字改为MLAPP JXqr3 Np1

    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。 TQ@d~GR

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;#/@+4@a&  
    1. 创建Matlab服务器。 vH[47CvG5  
    2. 移动探测面对于前一聚焦面的位置。 GW^,g@%C  
    3. 在探测面追迹光线 RFaSwf,5n  
    4. 在探测面计算照度 YB(Gk;]  
    5. 使用PutWorkspaceData发送照度数据到Matlab J^#:qk  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 t= #&fSR  
    7. 用Matlab画出照度数据 Z.PBu|Kx  
    8. 在Matlab计算照度平均值 z+{,WHjo  
    9. 返回数据到FRED中 lSwcL
