    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。 dH#o11[  
    YHvmo@  
    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: G]QD6b9~  
    enableservice('AutomationServer', true) "W\ #d  
    enableservice('AutomationServer') |\~cjPX(  
    eHPGzN Xb  
    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 w`F}3zm  
    ~Z.lvdA_5  
    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: 8Vl!&j0s^  
    1. 在FRED脚本编辑界面找到参考. R0oP##]  
    2. 找到Matlab Automation Server Type Library N{|N_}X`Y  
    3. 将名字改为MLAPP `=q)-y_C  
    pg4M$;ED  
    u'Mq^8  
    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。 `A&64D

    现在将脚本代码公布如下,此脚本执行如下几个步骤: # ?}WQP!  
    1. 创建Matlab服务器。 l~F,i n.  
    2. 移动探测面对于前一聚焦面的位置。 %S$P+B?

    5. 使用PutWorkspaceData发送照度数据到Matlab %z.u % %  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 }KS[(Q
