    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。 !Jn w_)  
    E!l1a5qB  
    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: KrG6z#)Uz  
    enableservice('AutomationServer', true) I/V#[KC  
    enableservice('AutomationServer') gO!h<1!  
    B^Mtj5Oc  
    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 wSF#;lqd  
    n$Fm~iPo,  
    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: B2WX#/lgd  
    1. 在FRED脚本编辑界面找到参考. oySM?ZE  
    2. 找到Matlab Automation Server Type Library Z9~Wlt'?  
    3. 将名字改为MLAPP )nxIxr0d-

    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。 EXzNehO~e

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /O9EI'40)  
    1. 创建Matlab服务器。 !sQ8,l0h  
    2. 移动探测面对于前一聚焦面的位置。 ua-|4@YO  
    3. 在探测面追迹光线 >g0@ Bk  
    4. 在探测面计算照度 x#mk[SV  
    5. 使用PutWorkspaceData发送照度数据到Matlab Vho0f<`E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {5-{f=Rk  
    7. 用Matlab画出照度数据 yS3s5C{C  
    8. 在Matlab计算照度平均值 *sVxjZvV  
    9. 返回数据到FRED中 (HKm2JuFG
