    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。 <Nkj)`%5iK  
    7q(RQQp  
    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: -`A6K!W&~p  
    enableservice('AutomationServer', true) &6!x;RB  
    enableservice('AutomationServer') tNq~M  
    \`x$@s?  
    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 rFGbp8(2  
    XC~|{d  
    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: uN'e~X6  
    1. 在FRED脚本编辑界面找到参考. tLLP2^_&  
    2. 找到Matlab Automation Server Type Library sv =6?uYW  
    3. 将名字改为MLAPP X62GEqff

    /SjA;c! .  
    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。 }+,;wj~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: JZ9w!)U  
    1. 创建Matlab服务器。 @/7tN3O  
    2. 移动探测面对于前一聚焦面的位置。 $(G.P!/  
    3. 在探测面追迹光线 :6%wVy5  
    4. 在探测面计算照度 /wKL"M-%  
    5. 使用PutWorkspaceData发送照度数据到Matlab yX/ 9jk  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6"z:s-V  
    7. 用Matlab画出照度数据 [>v.#:YM^  
    8. 在Matlab计算照度平均值 vDqmD{%4N
