    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。 Mu/(Xp62  
    &mtt,]6C_  
    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: ShC$ue?Q  
    enableservice('AutomationServer', true) P0>2}/;o  
    enableservice('AutomationServer') /Yi4j,8!|  
    mTu>S  
    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 \VhG'd3k

    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: &X:;B'   
    1. 在FRED脚本编辑界面找到参考. F&!vtlV)  
    2. 找到Matlab Automation Server Type Library cy@R i#  
    3. 将名字改为MLAPP FW8Zpr!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。 39O rY

    3. 在探测面追迹光线 #%QHb,lhl  
    4. 在探测面计算照度 |Io:D:  
    5. 使用PutWorkspaceData发送照度数据到Matlab N4,oO H~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 nxhlTf>3
