    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。 *K{-J*   
    q,ry3Nr4n  
    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: 0I8w'/s_g9  
    enableservice('AutomationServer', true) @AXRKYQ{t  
    enableservice('AutomationServer') w3l+BUn:X  
    8y<NT"  
    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 @_gCGI>Q  
    *r b/BZX{  
    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: SMMV$;O{9  
    1. 在FRED脚本编辑界面找到参考. m.F \Mn  
    2. 找到Matlab Automation Server Type Library Rmq8lU  
    3. 将名字改为MLAPP v4?qI >/  
    q'07

    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。 Ur`jmB

    现在将脚本代码公布如下,此脚本执行如下几个步骤: `)9nBZ  
    1. 创建Matlab服务器。 W[5a'}OV  
    2. 移动探测面对于前一聚焦面的位置。 _I("k:E7  
    3. 在探测面追迹光线 6#,VnS)`q  
    4. 在探测面计算照度 n9Mi?#xIp  
    5. 使用PutWorkspaceData发送照度数据到Matlab X1 A~#w>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 (<= &#e?  
    7. 用Matlab画出照度数据 x*8lz\w  
    8. 在Matlab计算照度平均值 Js`xTH'  
    9. 返回数据到FRED中 2wHvHH!
