    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。 =v8q  
    *0@e_h  
    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: HO>uS>+  
    enableservice('AutomationServer', true) ge|}'QKow  
    enableservice('AutomationServer') vEkz 5$  
    H{8\<E:V+}  
    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 d {4br  
    [(XKqiSV  
    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% u=G  
    1. 在FRED脚本编辑界面找到参考. {<lV=0]  
    2. 找到Matlab Automation Server Type Library U\N`[k.F  
    3. 将名字改为MLAPP ej~ /sO

    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。 J7H1<\=cJb

    现在将脚本代码公布如下,此脚本执行如下几个步骤: W$W7U|Z9y+  
    1. 创建Matlab服务器。 VCIG+Gz  
    2. 移动探测面对于前一聚焦面的位置。 Q_Rr5/  
    3. 在探测面追迹光线 =B\ ?(  
    4. 在探测面计算照度 97lwPjq  
    5. 使用PutWorkspaceData发送照度数据到Matlab uAP|ASH9T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ][Kj^7/  
    7. 用Matlab画出照度数据 R[b?kT-%  
    8. 在Matlab计算照度平均值 L(L;z'3y  
    9. 返回数据到FRED中 L_(|5#IDw
