    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。 fr8:L!9  
    @cNX\$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: RSG\3(  
    enableservice('AutomationServer', true) -"iGcVV  
        enableservice('AutomationServer') QfJ?'*  
    wn[q?|1  
    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 R_ojK&%  
    lL~T@+J~  
    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: /"+ n{*9  
    1. 在FRED脚本编辑界面找到参考. s4bLL  
    2. 找到Matlab Automation Server Type Library +5Yc/Qp  
        3. 将名字改为MLAPP .,[zI@9  
         $[iSZ;  
         =CEQYk-y1  
    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。 r# 5))q-

    现在将脚本代码公布如下,此脚本执行如下几个步骤: y\b.0-z  
    1. 创建Matlab服务器。 T<06y3sN  
    2. 移动探测面对于前一聚焦面的位置。 VL"!.^'c  
    3. 在探测面追迹光线 oop''6`C%  
    4. 在探测面计算照度 stz1e dP  
    5. 使用PutWorkspaceData发送照度数据到Matlab FLJdnL  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 hHF YAh   
    7. 用Matlab画出照度数据 .Ya]N+r*  
    8. 在Matlab计算照度平均值 P& C,EE$  
    9. 返回数据到FRED中 t0p^0
