    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。 T*J]e|aF  
    L2P~moVIi  
    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: zjM+F{P8  
    enableservice('AutomationServer', true) ?b2"~A  
    enableservice('AutomationServer') 1 W2AE?  
    (J\"\#/d  
    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 l *yml  
    u` `FD  
    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: a[xEN7L~4D  
    1. 在FRED脚本编辑界面找到参考. /JtKn*?}:>  
    2. 找到Matlab Automation Server Type Library fseHuL=~  
    3. 将名字改为MLAPP (Pin9^`ALc

    vov"60K  
    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:y M

    2. 移动探测面对于前一聚焦面的位置。 @wYuc{%S

    4. 在探测面计算照度 op"RrZAZBT  
    5. 使用PutWorkspaceData发送照度数据到Matlab C \H%4p1r  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 K S,X$)9
