    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。 ZQnJTS+Rd  
    |z|5j!Nfh  
    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: ?Gj$$IAe  
    enableservice('AutomationServer', true) FcsEv {#U  
    enableservice('AutomationServer') ^,b*.6t  
    l8%x(N4  
    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 P~i^V;g

    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: czb(&><  
    1. 在FRED脚本编辑界面找到参考. @iy ^a  
    2. 找到Matlab Automation Server Type Library ^Q4w<sX'  
    3. 将名字改为MLAPP 9ToM5oQ

    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。  #d*mG =  
    M,t8<y4 W/

    JXGIVH?Rpu  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: rc*&K#? B  
    1. 创建Matlab服务器。 2sy{  
    2. 移动探测面对于前一聚焦面的位置。 >;HbD p  
    3. 在探测面追迹光线 LlRvm/  
    4. 在探测面计算照度 ,^,Vq]$3  
    5. 使用PutWorkspaceData发送照度数据到Matlab L1Fn;nR  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &EmxSYL>  
    7. 用Matlab画出照度数据 dj?.Hc7od  
    8. 在Matlab计算照度平均值 2#*Bw=  
    9. 返回数据到FRED中 .ymR%X_k
