    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。 <_]W1V:0  
    gVy`||z  
    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: <@l j\,  
    enableservice('AutomationServer', true) )eqF21\  
    enableservice('AutomationServer') 7#Uzz"^  
    F/[m.!Eo  
    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 P,(_y8  
    X?;iSekI4  
    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: 9MQjSNYzo  
    1. 在FRED脚本编辑界面找到参考. #k[Y(_  
    2. 找到Matlab Automation Server Type Library ?YUL~P  
    3. 将名字改为MLAPP ==oJhB  
    G]{^.5  
    8EX?/33$  
    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。 Pc7p2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: DrbjklcUU  
    1. 创建Matlab服务器。 "@|rU4Y  
    2. 移动探测面对于前一聚焦面的位置。 P,xJVo\  
    3. 在探测面追迹光线 FMhuCl2  
    4. 在探测面计算照度 Q04 `+Vr  
    5. 使用PutWorkspaceData发送照度数据到Matlab `M. I.Z_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 MJCz %zK  
    7. 用Matlab画出照度数据 y y[Y=  
    8. 在Matlab计算照度平均值 3N|6?'m  
    9. 返回数据到FRED中 *-uzsq.W
