    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。 bf2B  
    6k%Lc4W  
    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: re-;s  
    enableservice('AutomationServer', true) pk&;5|cCD  
        enableservice('AutomationServer') 1p%75VW  
    &!=[.1H<  
    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 Y8$,So>~  
    xD|CQo}:  
    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: <Jwx|  
    1. 在FRED脚本编辑界面找到参考. sBuOKT/j  
    2. 找到Matlab Automation Server Type Library f(r=S Xa*  
        3. 将名字改为MLAPP 6 $k"B/k

    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。 BA 9c-Ay

    现在将脚本代码公布如下,此脚本执行如下几个步骤: i;GF/pi  
    1. 创建Matlab服务器。 zZ11J0UI  
    2. 移动探测面对于前一聚焦面的位置。 8qi6>}A  
    3. 在探测面追迹光线 m+ww  
    4. 在探测面计算照度 dQkp &.  
    5. 使用PutWorkspaceData发送照度数据到Matlab XX:?7:j}[8  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 &0='z  
    7. 用Matlab画出照度数据 {|Pg]#Wi&  
    8. 在Matlab计算照度平均值 OlwORtWzZ  
    9. 返回数据到FRED中 @VVDN
