    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。 )W)m?%  
    N2uxiXpQZ=  
    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: z]ZhvH7-  
    enableservice('AutomationServer', true) yfeX=h  
    enableservice('AutomationServer') kH1hsDe|&y  
    ]Mi ~vG q  
    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 oK&LYlU

    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: i rMZLc6  
    1. 在FRED脚本编辑界面找到参考. tLe!_p)  
    2. 找到Matlab Automation Server Type Library B" TZ8(<  
    3. 将名字改为MLAPP + 8 5]]}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。 *@=in7*c

    现在将脚本代码公布如下,此脚本执行如下几个步骤: #}L75  
    1. 创建Matlab服务器。 ^D\1F$AjC  
    2. 移动探测面对于前一聚焦面的位置。 B7(~m8:eH7  
    3. 在探测面追迹光线 :#58m0YLA:  
    4. 在探测面计算照度 4k_&Q?1  
    5. 使用PutWorkspaceData发送照度数据到Matlab sfi.zu G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8*3o 9$Pj  
    7. 用Matlab画出照度数据 wEENN_w  
    8. 在Matlab计算照度平均值 | 2BIAm]  
    9. 返回数据到FRED中 PHl{pE*
