    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。 Vsm%h^]d  
    ?%8})^Dd>4  
    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: Gdc ~Lh  
    enableservice('AutomationServer', true) 8CN7+V  
    enableservice('AutomationServer') 7DC0W|Fe  
    K~fDv  i  
    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 4N%2w(,+8

    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: I;kUG_c(4  
    1. 在FRED脚本编辑界面找到参考. )ZQ9a4%  
    2. 找到Matlab Automation Server Type Library .zSimEOF  
    3. 将名字改为MLAPP jl 30\M7

    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。 6qHvq A,

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ]C!Y~  
    1. 创建Matlab服务器。 hq&  
    2. 移动探测面对于前一聚焦面的位置。 ; ei<Q =[  
    3. 在探测面追迹光线 9L)&n.t1  
    4. 在探测面计算照度 .T62aJ   
    5. 使用PutWorkspaceData发送照度数据到Matlab oE|u;o  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 AT'_0> x8  
    7. 用Matlab画出照度数据 `pv89aO  
    8. 在Matlab计算照度平均值 0x9F*i_  
    9. 返回数据到FRED中 .$ P2W0G
