    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。 S x';Cj-  
    G"bItdb  
    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: 0xVue[ep  
    enableservice('AutomationServer', true) Z8P{Cr~U9  
    enableservice('AutomationServer') 5!r?U  
    ( w(GJ/g  
    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 a%"My;8  
    c|[:vin  
    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: @Y'BqDFlZ  
    1. 在FRED脚本编辑界面找到参考. 8[SiIuIV  
    2. 找到Matlab Automation Server Type Library H/>86GG  
    3. 将名字改为MLAPP 0^4uZeW?

    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。 =dD<[Iz6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: C2;qSKG3{m  
    1. 创建Matlab服务器。 "q(#,,_  
    2. 移动探测面对于前一聚焦面的位置。 JPQ[JD^]  
    3. 在探测面追迹光线 <o^_il$W  
    4. 在探测面计算照度 .%7#o  
    5. 使用PutWorkspaceData发送照度数据到Matlab wt4uzg8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 f} g)3+i  
    7. 用Matlab画出照度数据 cg$@x\fJ  
    8. 在Matlab计算照度平均值 5 T1M:~u i  
    9. 返回数据到FRED中 p#W[he
