    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。 <7 rK  
    g5Vr2  
    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:(-$"R  
    enableservice('AutomationServer', true) oL@ou{iQ  
    enableservice('AutomationServer') >(CoXSV5  
    v;Dcq  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 16y$;kf8

    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: [w/t  
    1. 在FRED脚本编辑界面找到参考. Z)A+ wM  
    2. 找到Matlab Automation Server Type Library rrWk&;?  
    3. 将名字改为MLAPP ##_Za6/n

    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。 *\WI!%

    1. 创建Matlab服务器。 eh>E).  
    2. 移动探测面对于前一聚焦面的位置。 &-:yn&f7  
    3. 在探测面追迹光线 G7;}309s  
    4. 在探测面计算照度 4sQAR6_SW~  
    5. 使用PutWorkspaceData发送照度数据到Matlab -],?kP  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Q75^7Ga_  
    7. 用Matlab画出照度数据 X-,y[ )  
    8. 在Matlab计算照度平均值 %`1vIr(7  
    9. 返回数据到FRED中 W~F/ZrT3A
