    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。 g*b 4N _  
    R"(rL5j  
    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: %bf+Y7m  
    enableservice('AutomationServer', true) xGbr>OqkTX  
    enableservice('AutomationServer') MWf]U  
    e;b,7Qw  
    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 o?\)!_Z|  
    `B+%W  
    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: 2}j2Bhc  
    1. 在FRED脚本编辑界面找到参考. T!$7:% D  
    2. 找到Matlab Automation Server Type Library =jD[A>3I  
    3. 将名字改为MLAPP 1@IRx{v$  
    0z?b5D;  
    &SS"A*xg  
    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。 Du3OmXMk

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \V@SCA'  
    1. 创建Matlab服务器。 rUfW0  
    2. 移动探测面对于前一聚焦面的位置。 4mOw[}@A  
    3. 在探测面追迹光线 E [JXQ76  
    4. 在探测面计算照度 5@c,iU-L  
    5. 使用PutWorkspaceData发送照度数据到Matlab g!n1]- 1  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >JT{~SRB|Y  
    7. 用Matlab画出照度数据 J*6I@_{/ U  
    8. 在Matlab计算照度平均值 ZCPK{Ru QE  
    9. 返回数据到FRED中 2rHw5Wn]~
