    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。 bL 9XQ:$C  
    (O`2$~mIM  
    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: NU/:jr.W#  
    enableservice('AutomationServer', true) %kXg|9Bx!  
    enableservice('AutomationServer') YCI- p p  
    g7g^iLU  
    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 gu|cQ2xV  
    6_a~ 4_#  
    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: --BS/L-  
    1. 在FRED脚本编辑界面找到参考. ^E}};CsT  
    2. 找到Matlab Automation Server Type Library < /\y<]b  
    3. 将名字改为MLAPP RS9mAeX4h  
    NB#-W4NA  
    dOx0'q"Z  
    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。 E%np-is{1

    1. 创建Matlab服务器。 >u/ T`$  
    2. 移动探测面对于前一聚焦面的位置。 $^Z ugD  
    3. 在探测面追迹光线 a%NSL6  
    4. 在探测面计算照度 m6iQB\ \  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5fuB((fd(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [W,}&  
    7. 用Matlab画出照度数据 TZ>_N;jTZ  
    8. 在Matlab计算照度平均值 TBr@F|RXiO  
    9. 返回数据到FRED中 aPH6R<G
