    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。 Y"dUxv1Ap  
    e!hy,O{Pw  
    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: b|'{f?  
    enableservice('AutomationServer', true) Pv#>j\OR&  
    enableservice('AutomationServer') aR0'$*3E  
    c?H@HoF  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 I"5VkeIx  
    cFF'ygJ/  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: CqkY_z  
    1. 在FRED脚本编辑界面找到参考. {^jk_G\ys  
    2. 找到Matlab Automation Server Type Library Q`{2 yU:r  
    3. 将名字改为MLAPP Q%Fa1h:2&  
    RP1sQ6$  
    \lBY4j+;  
    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。 ![l`@NH[U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: zHu w[  
    1. 创建Matlab服务器。 &hco3HfW  
    2. 移动探测面对于前一聚焦面的位置。 I #8TY/XP  
    3. 在探测面追迹光线 %m5&Y01  
    4. 在探测面计算照度 Rxfhk,I  
    5. 使用PutWorkspaceData发送照度数据到Matlab j+6`nN7L  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 l?Qbwv}  
    7. 用Matlab画出照度数据 %%h0 H[5*  
    8. 在Matlab计算照度平均值 A/A; '9  
    9. 返回数据到FRED中 XKQ\Ts2<k
