    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。 3F<VH  
    "%x<ttLl  
    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: N~xLu8,  
    enableservice('AutomationServer', true) g"> {9YE  
    enableservice('AutomationServer') '3 ^+{=q  
    ~Onoe $A[<  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ziCHjqT  
    D N*t~Z3[  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: "l*`>5Nn9  
    1. 在FRED脚本编辑界面找到参考. ?%y?rk <  
    2. 找到Matlab Automation Server Type Library W!&vul5  
    3. 将名字改为MLAPP O7$hYk

    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。 QD>"]ap,o

    1. 创建Matlab服务器。 [ra_ 2R  
    2. 移动探测面对于前一聚焦面的位置。 w:<W.7y?0  
    3. 在探测面追迹光线 ,5*eX  
    4. 在探测面计算照度 v3jg~"!  
    5. 使用PutWorkspaceData发送照度数据到Matlab \<)9?M :  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 PuZf/um  
    7. 用Matlab画出照度数据 <N9[?g)  
    8. 在Matlab计算照度平均值 y7i*s^ys{
