    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。 5W(S~}  
    2f=7`1RCD  
    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: !R`)S7!  
    enableservice('AutomationServer', true) fV\ eksBF  
    enableservice('AutomationServer') %)|_&Rh  
    p?#cn   
    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 HoFFce7o

    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: W8/8V,  
    1. 在FRED脚本编辑界面找到参考. cl4Vi%   
    2. 找到Matlab Automation Server Type Library )(Z)yz  
    3. 将名字改为MLAPP Z Rjqjx

    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。 Y?^1=9?6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: nCj_4,O  
    1. 创建Matlab服务器。 CXzN4!  
    2. 移动探测面对于前一聚焦面的位置。 dV5aIj  
    3. 在探测面追迹光线 f a9n6uT  
    4. 在探测面计算照度 a9OJC4\  
    5. 使用PutWorkspaceData发送照度数据到Matlab X+: >&&9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mJ>@Dh3>G  
    7. 用Matlab画出照度数据 $?dAO}f3O)  
    8. 在Matlab计算照度平均值 v7L} I[f  
    9. 返回数据到FRED中 uAWmg8
