    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。 ^75pV%<%  
     hgNY[,  
    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: n2H&t>N  
    enableservice('AutomationServer', true) [ +yGDMLs  
    enableservice('AutomationServer') D~XU `;~u  
    9$8X> T^   
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 u87=q^$

    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: l A 0-?k  
    1. 在FRED脚本编辑界面找到参考. & %@/Dwr  
    2. 找到Matlab Automation Server Type Library Fa6H(L3  
    3. 将名字改为MLAPP /vMQF+  
    p|xs|O6{  
    W` WLW8Qsw  
    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。 !k4 }v'=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: #i'C  
    1. 创建Matlab服务器。 i7Y s_8A"9  
    2. 移动探测面对于前一聚焦面的位置。 <>ZBW9  
    3. 在探测面追迹光线 FF5tPHB  
    4. 在探测面计算照度 |_xZ/DT  
    5. 使用PutWorkspaceData发送照度数据到Matlab Gsx^j?  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Nv}U/$$S  
    7. 用Matlab画出照度数据 &<\4q  
    8. 在Matlab计算照度平均值 we6+2  
    9. 返回数据到FRED中 }[XB]Xf
