    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。 :$~)i?ge<5  
    z Xx HaM  
    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: ARGtWW~:  
    enableservice('AutomationServer', true) J70#pF  
    enableservice('AutomationServer') O; 7`*}m  
    >k"Z'9l  
    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 JcL4q\g

    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: }A\s`H m  
    1. 在FRED脚本编辑界面找到参考. xeF0^p7Z  
    2. 找到Matlab Automation Server Type Library S}f 3b N  
    3. 将名字改为MLAPP brx 7hI

    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。 9fj3q>Un,

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {4J:t_<nKO  
    1. 创建Matlab服务器。 d]{wZ#x  
    2. 移动探测面对于前一聚焦面的位置。 @E;'Ffo  
    3. 在探测面追迹光线 @iwVU]j  
    4. 在探测面计算照度 Sio^FOTD  
    5. 使用PutWorkspaceData发送照度数据到Matlab |ZZl3l=]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 F7P?*!dx  
    7. 用Matlab画出照度数据 e&sZ]{uD  
    8. 在Matlab计算照度平均值 vikA  
    9. 返回数据到FRED中 : 8dQ8p;
