    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。 %-n) L  
    'cO8& |  
    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@|,1V!L  
    enableservice('AutomationServer', true) -@N-i$!;J  
    enableservice('AutomationServer') F.vRs|fk  
    nb_/1{F  
    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 0z=KnQx"4

    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: R~g|w4a@sC  
    1. 在FRED脚本编辑界面找到参考. J9T2 p\5  
    2. 找到Matlab Automation Server Type Library $?GggP d  
    3. 将名字改为MLAPP tc~gn!"

    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。 C*Q7@+&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: o0r&w;!  
    1. 创建Matlab服务器。 A]bb*a1  
    2. 移动探测面对于前一聚焦面的位置。 'w:ugb9]  
    3. 在探测面追迹光线 hW*o;o7u  
    4. 在探测面计算照度 jF6_yw  
    5. 使用PutWorkspaceData发送照度数据到Matlab U%vTmdOY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 }3z3GU8Q-  
    7. 用Matlab画出照度数据 Fs]N9],=I  
    8. 在Matlab计算照度平均值 |V34;}\4  
    9. 返回数据到FRED中 A'EI1_3{
