    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。 /^4)V8D_S  
    9oc[}k-M  
    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: F>^k<E?,C  
    enableservice('AutomationServer', true) *:YW@Gbm  
    enableservice('AutomationServer') K<s\:$VVh  
    5n(p 1OM2q  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 x!I7vs~~zW  
    rycscE4,  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: .Z/"L@  
    1. 在FRED脚本编辑界面找到参考. /eIwv 31  
    2. 找到Matlab Automation Server Type Library &X|z(vSJ$  
    3. 将名字改为MLAPP >Pv%E

    T*YdGIFO  
    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。 @Chj0wWZ>

    3. 在探测面追迹光线 7Kh+m@q.  
    4. 在探测面计算照度 YdeSJ(:  
    5. 使用PutWorkspaceData发送照度数据到Matlab a 2).Az  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 q=96Ci_a  
    7. 用Matlab画出照度数据 A`OU} 'v?L  
    8. 在Matlab计算照度平均值 4[Oy3.-c
