    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。 wyzBkRg.  
    yE|} 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: 8.%a"sxr  
    enableservice('AutomationServer', true) -IsdU7}  
    enableservice('AutomationServer') soVZz3F  
    i e)1h  
    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 pS@VLXZP  
    dR, NC-*  
    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: o` 1V  
    1. 在FRED脚本编辑界面找到参考. bZ22O"F  
    2. 找到Matlab Automation Server Type Library gJFpEA {  
    3. 将名字改为MLAPP l0_E9qh-i  
    OTHd1PSOu  
    }L7F g%,  
    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。 U*fj5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6p]R)K>wS  
    1. 创建Matlab服务器。 eKFc W5O  
    2. 移动探测面对于前一聚焦面的位置。 8qYGlew,  
    3. 在探测面追迹光线 )%@WoBRj  
    4. 在探测面计算照度 b%jG?HSu  
    5. 使用PutWorkspaceData发送照度数据到Matlab $HCAC 4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ABe^]HlH  
    7. 用Matlab画出照度数据 TNT"2FoBd  
    8. 在Matlab计算照度平均值 ,lS-;.  
    9. 返回数据到FRED中 ihY^~
