    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。 r5S/lp+Y+N  
    94ruQ/  
    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: 4/`;(*]Fv  
    enableservice('AutomationServer', true) O8$~dzf,2  
    enableservice('AutomationServer') Ge-Bk)6  
    px K&aY8  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 "d$~}=a[

    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: zvdut ,6<  
    1. 在FRED脚本编辑界面找到参考. 2wY|E<E  
    2. 找到Matlab Automation Server Type Library  'Y)aGH(  
    3. 将名字改为MLAPP A5yVxSF

    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。 e6j1Fa9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;(/go\m tB  
    1. 创建Matlab服务器。 n >y,{"J{  
    2. 移动探测面对于前一聚焦面的位置。 Uw.')ZY=  
    3. 在探测面追迹光线 6Bjo9,L  
    4. 在探测面计算照度 5N|LT8P}Z  
    5. 使用PutWorkspaceData发送照度数据到Matlab b`#YJpA  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Fk/I (Q  
    7. 用Matlab画出照度数据 w!20  
    8. 在Matlab计算照度平均值 kx;X:I(5&P  
    9. 返回数据到FRED中 Z\CvaX
