    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。 |Wo_5|E  
    CBj&8#8Z  
    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: , [ogh  
    enableservice('AutomationServer', true) T*m;G(  
    enableservice('AutomationServer') @|7Ma/8v  
    0O_acO 4  
    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 VW," dmC  
    ;'\#+GZ9p  
    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: .bwKG`F  
    1. 在FRED脚本编辑界面找到参考. vocXk_  
    2. 找到Matlab Automation Server Type Library >icL,n"]  
    3. 将名字改为MLAPP a.oZ}R7'Y

    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。 Glt%%TJb

    现在将脚本代码公布如下,此脚本执行如下几个步骤: oH[4<K>  
    1. 创建Matlab服务器。 ^5"2s:vP  
    2. 移动探测面对于前一聚焦面的位置。 Y<A593  
    3. 在探测面追迹光线 |fQl0hL  
    4. 在探测面计算照度 d;Uzl 1;  
    5. 使用PutWorkspaceData发送照度数据到Matlab =Wb!j18]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LTSoo.dE  
    7. 用Matlab画出照度数据 ]+ \]2`?  
    8. 在Matlab计算照度平均值 Sk'S`vH  
    9. 返回数据到FRED中 I eQF+Xz
