    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。 ?}!gLp  
    x(T!I&i={  
    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: \ZmFH8=|f  
    enableservice('AutomationServer', true) [v>Z(  
    enableservice('AutomationServer') Y:#kel<  
    MC[ `<W)u  
    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 y"%iD`{  
    "m<eHz]D  
    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: /;]B1T7  
    1. 在FRED脚本编辑界面找到参考. B[2h   
    2. 找到Matlab Automation Server Type Library D|8sjp4  
    3. 将名字改为MLAPP H_xQ>~b  
    (PE8H~d  
    3e!a>Gl*  
    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。 HquB*=^xh

    1. 创建Matlab服务器。 f"OA Zji  
    2. 移动探测面对于前一聚焦面的位置。 d%[`=fs]|m  
    3. 在探测面追迹光线 bo?3E +B  
    4. 在探测面计算照度 v;NZ"1=_  
    5. 使用PutWorkspaceData发送照度数据到Matlab F"HI>t)>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 0wa!pE"  
    7. 用Matlab画出照度数据 ,EGD8$RA]  
    8. 在Matlab计算照度平均值 +h9l %Pz  
    9. 返回数据到FRED中 ?AM 8*w
