    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。 _\LAWQ|M4[  
    b=+'i  
    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: bmO[9 )G  
    enableservice('AutomationServer', true) cv["Ps#;`W  
    enableservice('AutomationServer') DFt1{qS8@u  
    uIvE~<  
    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 ""ICdZ_A  
    y85/qg) H^  
    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: 6l>$N?a  
    1. 在FRED脚本编辑界面找到参考. $9\!CPZ2  
    2. 找到Matlab Automation Server Type Library Ij}RlYQz  
    3. 将名字改为MLAPP Y m|zM1qc

    2@aVoqrq#  
    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。 9Qb_BNUo

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <gKT7ONtg  
    1. 创建Matlab服务器。 fG5U' Vw  
    2. 移动探测面对于前一聚焦面的位置。 Pz1pEyuL  
    3. 在探测面追迹光线 ,P<n\(DQ  
    4. 在探测面计算照度 7!`,P  
    5. 使用PutWorkspaceData发送照度数据到Matlab /AP@Bhm  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 TCFx+*fBd  
    7. 用Matlab画出照度数据 AjK'P<:/  
    8. 在Matlab计算照度平均值  `' 5(4j  
    9. 返回数据到FRED中 ;X! sTs
