    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。 \[B#dw#  
    9Z3Y,`R,  
    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:  {qH+S/  
    enableservice('AutomationServer', true) j(_6.zf  
    enableservice('AutomationServer') 3|/zlKZz  
    +]C|y ,r  
    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 :%zAX  
    reoCyP\!!  
    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: !JjNm*F[  
    1. 在FRED脚本编辑界面找到参考. T(+*y  
    2. 找到Matlab Automation Server Type Library -li;w tCS  
    3. 将名字改为MLAPP w~e$ul(IQM

    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。 DwXSlsN3v

    现在将脚本代码公布如下,此脚本执行如下几个步骤: nh"LdHqiDB  
    1. 创建Matlab服务器。 @Y&(1Wl  
    2. 移动探测面对于前一聚焦面的位置。 9NC'iFQ#  
    3. 在探测面追迹光线 vH?3UW  
    4. 在探测面计算照度 *;<oM]W_  
    5. 使用PutWorkspaceData发送照度数据到Matlab @c%h fI  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 E-$N!KY  
    7. 用Matlab画出照度数据 M >s,I^  
    8. 在Matlab计算照度平均值 ~NwX,-ri  
    9. 返回数据到FRED中 >t $^U
