    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。 J Jy{@[m  
    "$8w.C  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: f z%tA39m  
    enableservice('AutomationServer', true) oh\1>3,Ns  
    enableservice('AutomationServer') B||c(ue  
    x!?Z *v@I  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 sXB+s  
    I:t^S.,  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ;r!\-]5$  
    1. 在FRED脚本编辑界面找到参考. w3bIb$12  
    2. 找到Matlab Automation Server Type Library [g|Hj)(  
    3. 将名字改为MLAPP l0`'5>

    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。 s.y}U5Ty?P

    现在将脚本代码公布如下,此脚本执行如下几个步骤: S=O$JP79  
    1. 创建Matlab服务器。 wLMvC{5  
    2. 移动探测面对于前一聚焦面的位置。 $L&BT 0  
    3. 在探测面追迹光线 f)^t')  
    4. 在探测面计算照度 0N VI +Z$  
    5. 使用PutWorkspaceData发送照度数据到Matlab U**)H_S/~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Z| L2oc e  
    7. 用Matlab画出照度数据 e\.HWV]I  
    8. 在Matlab计算照度平均值 F< |c4  
    9. 返回数据到FRED中 R 3G@ G
