    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。 JTl 37j  
    (a]'}c$X9`  
    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: ]?mWnEi!z  
    enableservice('AutomationServer', true) z`5+BL,|ND  
    enableservice('AutomationServer') GVn7#0x  
    nN/v7^^  
    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 r 'pFHX  
    h Sr#/dw&  
    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: rb&^ei9B  
    1. 在FRED脚本编辑界面找到参考. ]#))#-&1  
    2. 找到Matlab Automation Server Type Library uZ%b6+(  
    3. 将名字改为MLAPP L=4?vs  
    "uqa~R{

    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。 )^g}'V=vIr

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9?bfZF4A=  
    1. 创建Matlab服务器。 C6CX{IA]  
    2. 移动探测面对于前一聚焦面的位置。 DQH _@-q  
    3. 在探测面追迹光线 [$9sr=3:  
    4. 在探测面计算照度 SM! [ yC  
    5. 使用PutWorkspaceData发送照度数据到Matlab G:A ~nv9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 qmOGsj`#  
    7. 用Matlab画出照度数据 H>;km$b +  
    8. 在Matlab计算照度平均值 -:cS}I  
    9. 返回数据到FRED中 M1Od%nz3
