    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。 eX1<zzd  
    r^2>60q'  
    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: _rmTX.'w  
    enableservice('AutomationServer', true) vnrP;T=^  
    enableservice('AutomationServer') F^xhhz&e  
    ([+u U!  
    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 wQnW2)9!  
    ;n"Nv }<C  
    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: EU0b>2n4  
    1. 在FRED脚本编辑界面找到参考. [*jvvkAp  
    2. 找到Matlab Automation Server Type Library 7: cmBkXm  
    3. 将名字改为MLAPP GmJ4AYEP

    7w_cKR1;  
    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。 ._$tNGI4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <%~`!n,t0  
    1. 创建Matlab服务器。 js~?y|e8k  
    2. 移动探测面对于前一聚焦面的位置。 wE4:$+R};  
    3. 在探测面追迹光线 ~53uUT|B  
    4. 在探测面计算照度 2^*a$ OJ  
    5. 使用PutWorkspaceData发送照度数据到Matlab D^Cpgha  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @+,J^[ y  
    7. 用Matlab画出照度数据 K:osfd  
    8. 在Matlab计算照度平均值 Xc!0'P0T  
    9. 返回数据到FRED中 aJmSagr69C
