    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。 lg~7[=%k#  
    _]pu"hZz4  
    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: xZlCFu   
    enableservice('AutomationServer', true) V 3cKbk7~  
        enableservice('AutomationServer') aR/?YKA  
    [nPs  
    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 .\glNH1d  
    vIbM@Y4 '?  
    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: Vm>EF~r  
    1. 在FRED脚本编辑界面找到参考. JcA+ztPU  
    2. 找到Matlab Automation Server Type Library DQm%=ON7  
        3. 将名字改为MLAPP <.B+&3')  
         W>)0=8#\  
         hW< v5!,  
    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。 ?'9IgT[*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: O6R)>Y4  
    1. 创建Matlab服务器。 ABX%oZ7[|o  
    2. 移动探测面对于前一聚焦面的位置。 Bhd)# P  
    3. 在探测面追迹光线 .'gm2  
    4. 在探测面计算照度 Kbf(P95+uL  
    5. 使用PutWorkspaceData发送照度数据到Matlab pB 8D  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ?YLq iAA  
    7. 用Matlab画出照度数据 $2?AJ/2r$b  
    8. 在Matlab计算照度平均值 #e|o"R;/`  
    9. 返回数据到FRED中 z qo0P~
