    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。 N*;/~bt7 P  
    #/6X44 *u  
    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: cQ%HwYn  
    enableservice('AutomationServer', true) C2T,1=  
    enableservice('AutomationServer') U/X ^  
    p-_j0zv  
    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 k2a^gCBC  
    u^$ CR  
    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: rL/+`H  
    1. 在FRED脚本编辑界面找到参考. 3]Mx,u  
    2. 找到Matlab Automation Server Type Library 3m'6cMQ  
    3. 将名字改为MLAPP |ipppE=

    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。 6W o7q\"

    2. 移动探测面对于前一聚焦面的位置。 JP]K\nQx'  
    3. 在探测面追迹光线 )/Vr 5b@  
    4. 在探测面计算照度 X,b} d#\  
    5. 使用PutWorkspaceData发送照度数据到Matlab R:E:Y|&#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 g  YZgo  
    7. 用Matlab画出照度数据 Ra5cfkH;  
    8. 在Matlab计算照度平均值 zq#o8))4X  
    9. 返回数据到FRED中 ,$Mw/fA
