    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。 6k=*O|r  
    lf9mdbm  
    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: qS!U1R?s  
    enableservice('AutomationServer', true) Ivx]DXR|  
    enableservice('AutomationServer') olxnQYFo  
    Z.%0yS_T  
    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.ib"W#4  
    '}, 8x?  
    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: ">M:6\B  
    1. 在FRED脚本编辑界面找到参考. F&_b[xso7  
    2. 找到Matlab Automation Server Type Library /J5)_> R:  
    3. 将名字改为MLAPP $/FL)m8.3

    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。 2EC<8}CG

    现在将脚本代码公布如下,此脚本执行如下几个步骤: oIv\Xdc81  
    1. 创建Matlab服务器。 1~ZFkcV_C  
    2. 移动探测面对于前一聚焦面的位置。 *%n(t+'q  
    3. 在探测面追迹光线 L #`Vr$  
    4. 在探测面计算照度 uwc@~=;  
    5. 使用PutWorkspaceData发送照度数据到Matlab I\~sE Jwj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mO0}Go8  
    7. 用Matlab画出照度数据 giH WC%/  
    8. 在Matlab计算照度平均值 y41~  
    9. 返回数据到FRED中 :I(d-,C
