    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>XfbmQ(  
    N~)RR {$w  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: YLU.]UC  
    enableservice('AutomationServer', true) 6Qx[W>I  
    enableservice('AutomationServer') ]IM/R@  
    /h v2=A  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 \b6vu^;p  
    t}X+P`Ovq  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: yBYZ?gc  
    1. 在FRED脚本编辑界面找到参考. b+tm[@|,v  
    2. 找到Matlab Automation Server Type Library o+% ($p  
    3. 将名字改为MLAPP C(J+tbk  
    ZP(T=Q  
    UV#DN`%n  
    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。 >V$ S\"

    现在将脚本代码公布如下,此脚本执行如下几个步骤: GS@ Zc2JPF  
    1. 创建Matlab服务器。 Gl]z@ZXWIw  
    2. 移动探测面对于前一聚焦面的位置。 .:(T}\]R  
    3. 在探测面追迹光线 szw|`S>o  
    4. 在探测面计算照度 `Re{j{~s  
    5. 使用PutWorkspaceData发送照度数据到Matlab x4Wu`-4^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3:mZ1+  
    7. 用Matlab画出照度数据 y py  
    8. 在Matlab计算照度平均值 XbYST%| .  
    9. 返回数据到FRED中 ~LU$ no^
