    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。 X2i}vjkY  
    #\ n8M  
    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: 'fNKlPMv4D  
    enableservice('AutomationServer', true) B8%{}[q  
    enableservice('AutomationServer') TkO[rAC  
    h=_0+\%  
    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 0 Ir<y

    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: ;h" P{fF   
    1. 在FRED脚本编辑界面找到参考. [ $T(WGF  
    2. 找到Matlab Automation Server Type Library *(>}Y  
    3. 将名字改为MLAPP `VL}.h

    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。 U(;&(W"M

    1. 创建Matlab服务器。 d/e|'MPX  
    2. 移动探测面对于前一聚焦面的位置。 b (I2m  
    3. 在探测面追迹光线 ? j 9|5*  
    4. 在探测面计算照度 w7n373y%  
    5. 使用PutWorkspaceData发送照度数据到Matlab AkT<2H|4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 U"4?9. k  
    7. 用Matlab画出照度数据 V)i5=bHC  
    8. 在Matlab计算照度平均值 @ (i!Y L
