    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。 F<IqKgGzH  
    )#*c|.  
    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: rw+0<r3|K  
    enableservice('AutomationServer', true) B(^fM!_%-6  
    enableservice('AutomationServer') NG5H?hVN=  
    c%uhQ 62  
    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 ^T^U:Zdq  
    * k =L  
    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: $8_*LR$  
    1. 在FRED脚本编辑界面找到参考. S@_@hFV jd  
    2. 找到Matlab Automation Server Type Library 5l(;+#3y/  
    3. 将名字改为MLAPP |l)Oy#W  
    O8dDoP\F2  
    b[RBp0]x  
    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。 @X\nY</E#M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Z|wZyt$$  
    1. 创建Matlab服务器。 \N"K^kR4  
    2. 移动探测面对于前一聚焦面的位置。 8^< -;  
    3. 在探测面追迹光线 kO2im+y  
    4. 在探测面计算照度 xYwbbFGrG  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2M1yw "  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 D-,sF8{ i  
    7. 用Matlab画出照度数据 ZU "y<  
    8. 在Matlab计算照度平均值 6[qRb+ds  
    9. 返回数据到FRED中 dHOz;4_
