    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。 l7 +#gPA  
    *]ROUk@K=  
    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: )'<B\P/  
    enableservice('AutomationServer', true) } {! #` 's  
    enableservice('AutomationServer') )KZ1Z$<  
    xW$F-n  
    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 C~do*rnM^

    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: /`M> 3q[  
    1. 在FRED脚本编辑界面找到参考. T;cyU9  
    2. 找到Matlab Automation Server Type Library ]!u12^A{

    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。 IrAc&Ehul

    现在将脚本代码公布如下,此脚本执行如下几个步骤: V#j|_N1hm  
    1. 创建Matlab服务器。 ~c e?xr|  
    2. 移动探测面对于前一聚焦面的位置。 R&z)  
    3. 在探测面追迹光线 /UJ@e  
    4. 在探测面计算照度 rsbd DTy  
    5. 使用PutWorkspaceData发送照度数据到Matlab T&?0hSYt  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >28.^\?H4  
    7. 用Matlab画出照度数据 F1V[8I.0  
    8. 在Matlab计算照度平均值 U'pm5Mc\q
