    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。 (:pq77  
    1L nyWZ  
    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: @U{<a#  
    enableservice('AutomationServer', true) ({^9<Us  
        enableservice('AutomationServer') ::5E8919  
    a4 MZ;5  
    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 lrWQOYf2  
    +7V{ABfGl  
    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: Wg`AZ=t  
    1. 在FRED脚本编辑界面找到参考. (u3s"I d  
    2. 找到Matlab Automation Server Type Library Y&HK1>M_  
        3. 将名字改为MLAPP j*v40mXl`2  
         ccFn.($p?,  
         7nU6k%_%  
    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。 SqA J-_~

    2. 移动探测面对于前一聚焦面的位置。 bx4'en#  
    3. 在探测面追迹光线 !4"^`ors$  
    4. 在探测面计算照度 }n_p$g[Nj/  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5yZTcS z  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 LhXUm  
    7. 用Matlab画出照度数据 nlYR-.  
    8. 在Matlab计算照度平均值  +=q)  
    9. 返回数据到FRED中 i':i_kU
