    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。 1K(a=o[Ce  
    V.<$c1#=$  
    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: ~yacJU=  
    enableservice('AutomationServer', true) yLv jfP1  
    enableservice('AutomationServer') 2K >tI9);  
    jvfVB'Tmr  
    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 ]LGp3)T-

    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: ?t;>]Wo;  
    1. 在FRED脚本编辑界面找到参考. }m '= _u  
    2. 找到Matlab Automation Server Type Library g~q+a-  
    3. 将名字改为MLAPP ;VQFz&Q$u

    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。 t:A,pT3

    1. 创建Matlab服务器。 7lP3\7wD@9  
    2. 移动探测面对于前一聚焦面的位置。 5Gj?'Wov9  
    3. 在探测面追迹光线 wLa^pI4p ^  
    4. 在探测面计算照度 M :m-iX  
    5. 使用PutWorkspaceData发送照度数据到Matlab L,@O OBD  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9ICC2%j|  
    7. 用Matlab画出照度数据 5f54E|vD
