    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。 sQ>L3F;A`  
    1*u i|fuK  
    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: Kitx%P`i  
    enableservice('AutomationServer', true) Fi_JF;  
    enableservice('AutomationServer') j1U,X  
    *mTx0sQz(J  
    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 si.w1  
    t/L:Y=7w  
    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: s6| S#  
    1. 在FRED脚本编辑界面找到参考. P<{N)H 2r  
    2. 找到Matlab Automation Server Type Library tp3]?@0  
    3. 将名字改为MLAPP "~^ #{q  
    z~y=(T  
    ilpP"B  
    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。 Uel^rfE`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: X23#y7:  
    1. 创建Matlab服务器。 cas5  
    2. 移动探测面对于前一聚焦面的位置。 ^CWxYDG*  
    3. 在探测面追迹光线 Uc<j{U ,  
    4. 在探测面计算照度 jX8,y  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9j~|m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~v+A6N:qC  
    7. 用Matlab画出照度数据 5fqQ;r  
    8. 在Matlab计算照度平均值 F2 #s^4Ii  
    9. 返回数据到FRED中  YD|;xuh
