    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。 -Crm#Ib~  
    0 ~^l*  
    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: =EQaZ8k  
    enableservice('AutomationServer', true) ,: Z7P@  
    enableservice('AutomationServer') (4Ha'uqz  
    l", X  
    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 QqCwyK0  
    +&*Ybbhb  
    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: Rl[SqmnI)@  
    1. 在FRED脚本编辑界面找到参考. YGsg0I't  
    2. 找到Matlab Automation Server Type Library D&|HS!  
    3. 将名字改为MLAPP {D`_q|

    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。 v&3 Oc

    2. 移动探测面对于前一聚焦面的位置。 = 6.i.(L_S

    4. 在探测面计算照度 H|I.h{:  
    5. 使用PutWorkspaceData发送照度数据到Matlab .-?Txkwb  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <uXQT$@?  
    7. 用Matlab画出照度数据 J5L[)Gd)D
