    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。 !$r4 lu  
    J+IQvOn_|  
    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: x]|8  
    enableservice('AutomationServer', true) p.,o@GcL~  
    enableservice('AutomationServer') |5|^[v   
    e<s56<3j  
    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 qa 'YZE`  
    6B 4Sd  
    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: 'vKB]/e;  
    1. 在FRED脚本编辑界面找到参考. Q7oJ4rIP  
    2. 找到Matlab Automation Server Type Library :|/bEP]p/  
    3. 将名字改为MLAPP Cw1Jl5OVZ  
    c(jF^ 0~  
    ro{q':Z3  
    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。 *oLAO/)n

    [v$_BS#u^3  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: .U|e#t  
    1. 创建Matlab服务器。 '^pA%I2D  
    2. 移动探测面对于前一聚焦面的位置。 ZC+F*:$  
    3. 在探测面追迹光线 oK1"8k|Z  
    4. 在探测面计算照度 -'& 4No  
    5. 使用PutWorkspaceData发送照度数据到Matlab c$aTl9e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 HPVW2Y0_N  
    7. 用Matlab画出照度数据 p] kpDx[9  
    8. 在Matlab计算照度平均值 &Npv~Iy  
    9. 返回数据到FRED中 It,m %5 Py
