    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。 2 E= L8<  
    wC*X4 '  
    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: <3 uNl  
    enableservice('AutomationServer', true) gG uO  
    enableservice('AutomationServer') .\mj4*?/  
    S jj6q`  
    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 p7 ~!z.)o

    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: Q{/Ef[(a@  
    1. 在FRED脚本编辑界面找到参考. xD7]C|8o  
    2. 找到Matlab Automation Server Type Library g)B]FH1

    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。 n{jGOfc

    1. 创建Matlab服务器。 atzX;@"K  
    2. 移动探测面对于前一聚焦面的位置。 |BYRe1l6l  
    3. 在探测面追迹光线 @9:uqsL  
    4. 在探测面计算照度 |[lKY+26:{  
    5. 使用PutWorkspaceData发送照度数据到Matlab kf9X$d6
