    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。 A~L Ti  
    J,=^'K(  
    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: #O'g*]j  
    enableservice('AutomationServer', true) }5X.*wz  
    enableservice('AutomationServer') TI8E W  
    EE qlsH  
    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 fo I:`]2"*

    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: $% W.=a'5  
    1. 在FRED脚本编辑界面找到参考. #4Cf-$J  
    2. 找到Matlab Automation Server Type Library _G)x\K]N  
    3. 将名字改为MLAPP nH[>Sff$  
    UG<<.1JL

    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。 2$gFiZ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >rFM8P(  
    1. 创建Matlab服务器。 \<b42\a}  
    2. 移动探测面对于前一聚焦面的位置。 E7]a#  
    3. 在探测面追迹光线 ^9|&w.:@Q  
    4. 在探测面计算照度 FWS!b!#,N  
    5. 使用PutWorkspaceData发送照度数据到Matlab Xd&oERJj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >lugHF$G  
    7. 用Matlab画出照度数据 Fk?KR  
    8. 在Matlab计算照度平均值 D6EqJ,~
