    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。 n{(,r'  
    *X uIA-9  
    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: 7Qd boEa  
    enableservice('AutomationServer', true) k>F>y|m  
        enableservice('AutomationServer') :Q ?p^OC  
    VE)) `?  
    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 ;sAe#b  
    )Lg~2]'?j  
    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: J"K(nKXO_?  
    1. 在FRED脚本编辑界面找到参考. QYps5zcn  
    2. 找到Matlab Automation Server Type Library =g|5VXW5  
        3. 将名字改为MLAPP qNWSDZQ  
         }b^x#HC  
         i,2eoM)FB  
    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。 afE8Kqa:H

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 63QF1*gPH  
    1. 创建Matlab服务器。 HV{W7)  
    2. 移动探测面对于前一聚焦面的位置。 wW7#M  
    3. 在探测面追迹光线 NH4T*R)Vz  
    4. 在探测面计算照度 8WpZ "  
    5. 使用PutWorkspaceData发送照度数据到Matlab M7{_"9X{  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 B & ]GGy  
    7. 用Matlab画出照度数据 0nZQ" {x  
    8. 在Matlab计算照度平均值 v oO7W"  
    9. 返回数据到FRED中 +1^L35\@
