    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。 7DPxz'7):  
    JLak>MS  
    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: nIWY<Z"  
    enableservice('AutomationServer', true) {_R{gpj'  
    enableservice('AutomationServer') qH4+i STnV  
    rtdEIk  
    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 gE9x+g  
    ,*.qa0E#W  
    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: AD~_n ^  
    1. 在FRED脚本编辑界面找到参考. sV;q(,oru  
    2. 找到Matlab Automation Server Type Library K]&i9`>N   
    3. 将名字改为MLAPP (tCBbPW6T?  
    wlFK#iK  
    FA{'Ki`  
    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。 AAF']z<4_"

    现在将脚本代码公布如下,此脚本执行如下几个步骤: vDIsawbHD  
    1. 创建Matlab服务器。 q)3QmA~  
    2. 移动探测面对于前一聚焦面的位置。 b$sT`+4q  
    3. 在探测面追迹光线 }.D adV  
    4. 在探测面计算照度 r72zWpF!Ss  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]sI\.a  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `S A1V),~  
    7. 用Matlab画出照度数据 d~q7!  
    8. 在Matlab计算照度平均值 [QIQpBL  
    9. 返回数据到FRED中 0jt@|3
