    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"mlM  
    3q'&j, ,^  
    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: @~#Ym1{W  
    enableservice('AutomationServer', true) :k3Nt5t!  
    enableservice('AutomationServer') ;Wl+ zw  
    aS pWsT  
    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 w^#L9i'v'

    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: Fb4`|  
    1. 在FRED脚本编辑界面找到参考. m <w "T7  
    2. 找到Matlab Automation Server Type Library &CIVL#];e  
    3. 将名字改为MLAPP TP"1\O

    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。 OzQ -7|m'J

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4lM8\Lr  
    1. 创建Matlab服务器。 j8n4fv-)f  
    2. 移动探测面对于前一聚焦面的位置。 gCN$}  
    3. 在探测面追迹光线 Vm df8[5  
    4. 在探测面计算照度 G <uyin>  
    5. 使用PutWorkspaceData发送照度数据到Matlab hTEx]# (  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ^kgBa27  
    7. 用Matlab画出照度数据 l%`F&8K  
    8. 在Matlab计算照度平均值 ?qX)ihe%k  
    9. 返回数据到FRED中 vi|R(&
