    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。 9A}y^=!`  
    x7xQrjE  
    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: +Lo,*  
    enableservice('AutomationServer', true) ^HHT>K-m  
    enableservice('AutomationServer') D@k#'KU  
    s##XC^;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 'ztY>KVj  
    8Z 0@-8vi  
    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: ;3Q3!+%j  
    1. 在FRED脚本编辑界面找到参考. *4l6+#W  
    2. 找到Matlab Automation Server Type Library T\Jm=+]c!  
    3. 将名字改为MLAPP PW9tZx#

    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。 NF7+Gp6?q

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 5g2:o^  
    1. 创建Matlab服务器。 _ n4C~  
    2. 移动探测面对于前一聚焦面的位置。 mf2Qu  
    3. 在探测面追迹光线 h6D1uM"o   
    4. 在探测面计算照度 Qaiqx"x3  
    5. 使用PutWorkspaceData发送照度数据到Matlab *bi;mQ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 T`Xz*\}Zb  
    7. 用Matlab画出照度数据 kB-<17  
    8. 在Matlab计算照度平均值 i"{znKz vD  
    9. 返回数据到FRED中 q]y{ 4"=5
