    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。 15J"iN2"W  
    Szt2 "AR  
    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: 8?LT*>!  
    enableservice('AutomationServer', true) Z#@  
    enableservice('AutomationServer') U:8] G  
    f$^wu~  
    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 A"pQOtrm\k

    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: R /" f  
    1. 在FRED脚本编辑界面找到参考. AHn!>w,  
    2. 找到Matlab Automation Server Type Library ,*W~M&n"m  
    3. 将名字改为MLAPP a6 vej

    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。 F<{,W-my `

    1. 创建Matlab服务器。 "|I.j)  
    2. 移动探测面对于前一聚焦面的位置。 V5$ Gb6?K

    5. 使用PutWorkspaceData发送照度数据到Matlab )rP,+B?W  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vrb@::sy0T  
    7. 用Matlab画出照度数据 rzHBop-8  
    8. 在Matlab计算照度平均值 h(yFr/  
    9. 返回数据到FRED中 V~*>/2+
