    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。 M0)0~#?.D  
    >o& %via}  
    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: 7i02M~*uS  
    enableservice('AutomationServer', true) L*4= b (3  
    enableservice('AutomationServer') y@2"[fo3~  
    BXxJra/V  
    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 M%Vp_ 0

    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: kVt/Hhd9  
    1. 在FRED脚本编辑界面找到参考.  rf'A+q  
    2. 找到Matlab Automation Server Type Library w}(pc }^U  
    3. 将名字改为MLAPP ZZ :*c"b:  
    Fe$o*r,  
    0(Z:QqpU$  
    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。 /P46k4M1U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: QG L~??  
    1. 创建Matlab服务器。 60e{]}Z  
    2. 移动探测面对于前一聚焦面的位置。 '0_W< lGB  
    3. 在探测面追迹光线 Q?([#  
    4. 在探测面计算照度 $/(``8li_  
    5. 使用PutWorkspaceData发送照度数据到Matlab Hv:~)h$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )Wt&*WMFXl  
    7. 用Matlab画出照度数据 8NE[L#k  
    8. 在Matlab计算照度平均值 `jhbKgR[  
    9. 返回数据到FRED中 10r!p: D
