    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。 %%d3M->C}  
    gt]k#(S  
    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: oN3DM;  
    enableservice('AutomationServer', true) qaE>])  
        enableservice('AutomationServer') /Mq9~oC  
    V ,# |\  
    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 =zaf{0c  
    /qf(5Bm  
    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: ?w/i;pp<,  
    1. 在FRED脚本编辑界面找到参考. CYkU-  
    2. 找到Matlab Automation Server Type Library d'p]F~a  
        3. 将名字改为MLAPP \mGx-g6  
         EL/~c*a/  
         ?xkw~3Yfi  
    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。 2H\ }N^;f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K+WbxovXU  
    1. 创建Matlab服务器。 $r3kAM;V:  
    2. 移动探测面对于前一聚焦面的位置。 |j2b=0Rpk  
    3. 在探测面追迹光线 S=f:-?N|  
    4. 在探测面计算照度 r>o#h+'AV  
    5. 使用PutWorkspaceData发送照度数据到Matlab /sU~cn^D5  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ML:Zm~A1U  
    7. 用Matlab画出照度数据 5f#N$mh  
    8. 在Matlab计算照度平均值 /J@<e{&t~  
    9. 返回数据到FRED中 . {\lbI
