    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。 =<icHt6s  
    eA_4,"{  
    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: 1:8: yFV  
    enableservice('AutomationServer', true) HF:PF"|3  
        enableservice('AutomationServer') it@s(1EO#  
    FB`HwE<  
    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 f #14%?/

    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: TUt)]"h<  
    1. 在FRED脚本编辑界面找到参考. =T`-h"E~@  
    2. 找到Matlab Automation Server Type Library jXQ_7  
        3. 将名字改为MLAPP 1d6pQ9 N  
         X"sN~Q.0  
         H'.d'OE:I  
    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。 E'}$'n?:

    1. 创建Matlab服务器。 *W  l{2&  
    2. 移动探测面对于前一聚焦面的位置。 @2<J_Ja  
    3. 在探测面追迹光线 jEadVM9  
    4. 在探测面计算照度 &}ow-u9c3  
    5. 使用PutWorkspaceData发送照度数据到Matlab g`1i[Iu2  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 [iD!!{6+  
    7. 用Matlab画出照度数据 {iRNnh   
    8. 在Matlab计算照度平均值 * gnL0\*  
    9. 返回数据到FRED中 [F$3mzx
