    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。 5;@2SY7 ,  
    +:3s f%0  
    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: _%KRZx}  
    enableservice('AutomationServer', true) Ij2T h]  
    enableservice('AutomationServer') 3$4I  
    i hcSSUm  
    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 }CM#jN?(  
    I{i6e'.jP  
    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: 4ufT-&m};s  
    1. 在FRED脚本编辑界面找到参考. Yy0U2N [i  
    2. 找到Matlab Automation Server Type Library U;#G $  
    3. 将名字改为MLAPP :Z.P0=  
    NtNCt;_R7  
    #xh M&X  
    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。 nT9Hw~f<j

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |]eWO#vs  
    1. 创建Matlab服务器。 7U:{=+oLR  
    2. 移动探测面对于前一聚焦面的位置。 =g|5VXW5  
    3. 在探测面追迹光线 _wUg+Xs]  
    4. 在探测面计算照度 \$!D^%~;  
    5. 使用PutWorkspaceData发送照度数据到Matlab Uf9L*Z'6il  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "a-;?S&  
    7. 用Matlab画出照度数据 xy-Vw"I[bh  
    8. 在Matlab计算照度平均值 +z<GycIc?K  
    9. 返回数据到FRED中 F_@?'#m
