    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。 ] `q]n  
    )/Eu=+d  
    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: rx9y^E5T`;  
    enableservice('AutomationServer', true) {SXSQ'=  
    enableservice('AutomationServer') S#yGqN0i  
    v#s*I/kw  
    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 [7 r^fD A  
    o-l-Z|)7  
    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: S!gzmkGcj  
    1. 在FRED脚本编辑界面找到参考. [S~Bt78d%r  
    2. 找到Matlab Automation Server Type Library dcq18~  
    3. 将名字改为MLAPP 1$C?+H  
    HIE8@Rv/3  
    j6k"%QHf  
    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。 (.Ak*

    3. 在探测面追迹光线 kkb+qo  
    4. 在探测面计算照度 &!WRa@x0I  
    5. 使用PutWorkspaceData发送照度数据到Matlab Qmo}esb'(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 r1vS~ 4Z  
    7. 用Matlab画出照度数据 @+p(%  
    8. 在Matlab计算照度平均值 M?}:N_9<J  
    9. 返回数据到FRED中 o37oRv]
