    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。 /bfsC& 3  
    /_26D0}UuF  
    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: 9oc.`-e\?  
    enableservice('AutomationServer', true) }4A+J"M4y  
    enableservice('AutomationServer') j= ]WAjT  
    &qMSJ  
    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 -.ha\t0J

    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: NnrX64|0  
    1. 在FRED脚本编辑界面找到参考. C1r]kF  
    2. 找到Matlab Automation Server Type Library /G G QO$'  
    3. 将名字改为MLAPP @e$z Ej5  
    lwQI 9U[O2  
    m)=  -sD  
    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。 /3'-+bp^=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: J@p[v3W  
    1. 创建Matlab服务器。 iNd 8M V  
    2. 移动探测面对于前一聚焦面的位置。 :T5l0h-eC  
    3. 在探测面追迹光线 k3}ymhUf  
    4. 在探测面计算照度 cDm_QYQ  
    5. 使用PutWorkspaceData发送照度数据到Matlab I$9 t^82j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 yZUB8erb.  
    7. 用Matlab画出照度数据 cl^wLC'o  
    8. 在Matlab计算照度平均值 o_b j@X  
    9. 返回数据到FRED中 9_ KUUA
