    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。 5,,b>Z<  
    M&/([ >Q  
    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: NPFrn[M$  
    enableservice('AutomationServer', true) f L}3I(VK  
    enableservice('AutomationServer') d;-/F b{4  
    j18qY4Gw)  
    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 ^q$m>|KI  
    `]0E)  
    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: REe<k<>p~  
    1. 在FRED脚本编辑界面找到参考. u*aFWl]=  
    2. 找到Matlab Automation Server Type Library c@]_V  
    3. 将名字改为MLAPP MBO3y&\S4

    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。 GF3"$?Cw

    现在将脚本代码公布如下,此脚本执行如下几个步骤: j%V95M% $  
    1. 创建Matlab服务器。 mqx#N%  
    2. 移动探测面对于前一聚焦面的位置。 wj'5D0   
    3. 在探测面追迹光线 z'(][SB  
    4. 在探测面计算照度 YjT7_|`(]  
    5. 使用PutWorkspaceData发送照度数据到Matlab Pl>S1  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 V\ 7O)g  
    7. 用Matlab画出照度数据 \+STl#3*q  
    8. 在Matlab计算照度平均值 h dw~AGO#  
    9. 返回数据到FRED中 KqE5{ q
