    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。 #h=V@Dh  
    ivo><"Y(r  
    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 @Sz/  
    enableservice('AutomationServer', true) 0<`qz |_h  
    enableservice('AutomationServer') jV*10kM<  
    C%yH}T\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 TzaeE

    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: AQjv? 4)T  
    1. 在FRED脚本编辑界面找到参考. q$" u<  
    2. 找到Matlab Automation Server Type Library G>vK$W$f N  
    3. 将名字改为MLAPP 6NV592

    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。 9]=J+ (M

    3. 在探测面追迹光线 'hr_g* i  
    4. 在探测面计算照度 u|IS7>Sm  
    5. 使用PutWorkspaceData发送照度数据到Matlab D@uVb4uK  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :(US um  
    7. 用Matlab画出照度数据 t jThQ  
    8. 在Matlab计算照度平均值 87!jn'A  
    9. 返回数据到FRED中 ~F-knEvL
