    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。 VVJIJ9L&C  
    cq0-D d9^&  
    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: 3O*^[$vM  
    enableservice('AutomationServer', true) w ZfY~  
    enableservice('AutomationServer') +"1fr  
    p1UYkmx[  
    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 3 <)+)n  
    zfw=U \  
    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: m6uFmU*<M}  
    1. 在FRED脚本编辑界面找到参考. k8c(|/7d  
    2. 找到Matlab Automation Server Type Library #y-R*4G  
    3. 将名字改为MLAPP JNv@MJb}  
    {l"(EeW6)  
    +ib&6IU  
    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。 K7X*N

    1. 创建Matlab服务器。 iPdS>e e  
    2. 移动探测面对于前一聚焦面的位置。 \%&):OD1  
    3. 在探测面追迹光线 :T{VCw:*  
    4. 在探测面计算照度 I? ="Er[g}  
    5. 使用PutWorkspaceData发送照度数据到Matlab f0879(,i  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xX|f{)<  
    7. 用Matlab画出照度数据 }kG>6_p?  
    8. 在Matlab计算照度平均值 : { iK 5
