    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。 /nas~{B  
    dum(T  
    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: w$1B|7tX;2  
    enableservice('AutomationServer', true) 6Ex 16  
    enableservice('AutomationServer') r 1x2)  
    u P&<  
    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 Fd(o8z8Q  
    8`GN8 F  
    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: "t!_b ma  
    1. 在FRED脚本编辑界面找到参考. IL&;2%  
    2. 找到Matlab Automation Server Type Library E$1P H)  
    3. 将名字改为MLAPP MLk%U 4  
    p1`") $

    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。 kmZ  U;Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *:tfz*FG$G  
    1. 创建Matlab服务器。 z\zqmW6  
    2. 移动探测面对于前一聚焦面的位置。 2Cgq&\wS  
    3. 在探测面追迹光线 \{K~x@`  
    4. 在探测面计算照度 og)f?4  
    5. 使用PutWorkspaceData发送照度数据到Matlab oa q!<lI  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $s,Az_bs  
    7. 用Matlab画出照度数据 l1uv]t <  
    8. 在Matlab计算照度平均值 I\WBPI  
    9. 返回数据到FRED中 kBr?Q
