    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。 );5H<[  
    iwT PJGK|  
    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: L)j<;{J/Q0  
    enableservice('AutomationServer', true) rnTjw "%  
    enableservice('AutomationServer') *4|]=yPU  
    ^N:bT;;$nZ  
    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 [&a=vE  
    ,[<+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: B1Cu?k);.  
    1. 在FRED脚本编辑界面找到参考. l^%W/b>?b  
    2. 找到Matlab Automation Server Type Library =F"vL  
    3. 将名字改为MLAPP  a EmLf

    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。 P+t`Rw

    现在将脚本代码公布如下,此脚本执行如下几个步骤: C(kIj  
    1. 创建Matlab服务器。 &a bR}J[  
    2. 移动探测面对于前一聚焦面的位置。 8[xl3=  
    3. 在探测面追迹光线 1A.ecv'  
    4. 在探测面计算照度 x l4A<  
    5. 使用PutWorkspaceData发送照度数据到Matlab tDIQ=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 L:E?tR}H  
    7. 用Matlab画出照度数据 X(*MHBd  
    8. 在Matlab计算照度平均值 6#DDMP8;I  
    9. 返回数据到FRED中 hO] vy>i;
