    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。 6/ `.(fL1  
    ]h9!ei [  
    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: _e!F~V.  
    enableservice('AutomationServer', true) voe7l+Xk  
    enableservice('AutomationServer') ]8;n{ }X  
    j'p1q  
    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 UMN*]_'+;b

    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: @InZ<AW>|  
    1. 在FRED脚本编辑界面找到参考. V#q}Wysft  
    2. 找到Matlab Automation Server Type Library bqx0d=Z~[  
    3. 将名字改为MLAPP 1t9.fEmT

    W@\ (nfD2  
    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。 Jg$xO@.

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K^t?gt@k}  
    1. 创建Matlab服务器。 uENdI2EY8y  
    2. 移动探测面对于前一聚焦面的位置。 2yo cu!4l  
    3. 在探测面追迹光线 insY(.N  
    4. 在探测面计算照度 nF)uTk  
    5. 使用PutWorkspaceData发送照度数据到Matlab W2wpcc  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _w ]4~V9  
    7. 用Matlab画出照度数据 1f (DU4h  
    8. 在Matlab计算照度平均值 N6Z{BLZ  
    9. 返回数据到FRED中 s4T}Bs r
