    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。 420K fVA  
    W%x#ps5%  
    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: `Jo}/c 5R  
    enableservice('AutomationServer', true) Rp1OC  
    enableservice('AutomationServer') 7O j9~3o4  
    oUH\SW8?  
    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 ;#*mB`  
    TM9>r :j'  
    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: ?Z"}RMM)8  
    1. 在FRED脚本编辑界面找到参考. Q{l;8MCL  
    2. 找到Matlab Automation Server Type Library 6Z 7$ZQ~  
    3. 将名字改为MLAPP dpS  
    OpfFF;"A'  
    #i? TCO  
    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。 ! JN@4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =KMck=#B  
    1. 创建Matlab服务器。 7G(X:!   
    2. 移动探测面对于前一聚焦面的位置。 K4~dEZ   
    3. 在探测面追迹光线 LcXrD+ 1  
    4. 在探测面计算照度 ;:OJQFu%4  
    5. 使用PutWorkspaceData发送照度数据到Matlab am=56J$ig  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 x!J L9  
    7. 用Matlab画出照度数据 9%8T09I!  
    8. 在Matlab计算照度平均值 F+X3CB,f  
    9. 返回数据到FRED中 Mg].#
