    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。 ) hPVX()O!  
    3&'R1~Vh  
    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: vcD'~)G(*  
    enableservice('AutomationServer', true) &1$8q0  
    enableservice('AutomationServer') AuM:2N2  
    ~g96o81V  
    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 =[8d@d\  
    `QAh5r"  
    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: Pb=rFas*C  
    1. 在FRED脚本编辑界面找到参考. wO\!xW:  
    2. 找到Matlab Automation Server Type Library j<|6s,&  
    3. 将名字改为MLAPP &*c'uN w  
    c( 8W8R  
    Lj-{t% }  
    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。 a:xgjUt&5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: n K0hTQ  
    1. 创建Matlab服务器。 iqlVlm>E  
    2. 移动探测面对于前一聚焦面的位置。 a#6,#Q"  
    3. 在探测面追迹光线 9M19 UP&  
    4. 在探测面计算照度 |7Yvq%E  
    5. 使用PutWorkspaceData发送照度数据到Matlab _.hIv8V  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 z'v9j_\  
    7. 用Matlab画出照度数据 Dl@{}9  
    8. 在Matlab计算照度平均值 hG[4O3jo\  
    9. 返回数据到FRED中 dR%q1Y&`
