    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。 ^a #  
    k>W}9^ cK  
    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: 8;+dlWp  
    enableservice('AutomationServer', true) L`@)*x)~R  
    enableservice('AutomationServer') e00s*LdC  
    i^_?C5  
    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 f)9{D[InM^

    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: qV&ai{G:  
    1. 在FRED脚本编辑界面找到参考. JXKo zy41  
    2. 找到Matlab Automation Server Type Library QKt+Orz  
    3. 将名字改为MLAPP \ x>#bql+

    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。 Fb^f`UI

    1. 创建Matlab服务器。 cjyb:gAO  
    2. 移动探测面对于前一聚焦面的位置。 I?#B_R#  
    3. 在探测面追迹光线 csCi0'u  
    4. 在探测面计算照度 2& ZoG%)  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6SVh6o@]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 oV,lEXz  
    7. 用Matlab画出照度数据 &8'QD~
