    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。 AUxLch+"5K  
    3vmLftZE}  
    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: Bn47O~  
    enableservice('AutomationServer', true) 0XL x@FYn  
    enableservice('AutomationServer') (!{_O_&  
    1 dI  
    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 ZXHG2@E)

    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: A^%z;( 0p  
    1. 在FRED脚本编辑界面找到参考. OsvAm'B  
    2. 找到Matlab Automation Server Type Library D OPOzh  
    3. 将名字改为MLAPP >0:h(,?V

    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。 !tHqF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0>VgO{X  
    1. 创建Matlab服务器。 9v<BO$ ,a  
    2. 移动探测面对于前一聚焦面的位置。 a5z.c_7r  
    3. 在探测面追迹光线 9?bfZF4A=  
    4. 在探测面计算照度 [,|KVc=&H  
    5. 使用PutWorkspaceData发送照度数据到Matlab U: gE:tf  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mmr>"`5.  
    7. 用Matlab画出照度数据 Wky~hm  
    8. 在Matlab计算照度平均值 Joq9.%7Q  
    9. 返回数据到FRED中 x-CY G?-x
