    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。 ,*&G1|_6  
    U\veOQ;mW  
    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: [zL7Q^~  
    enableservice('AutomationServer', true) masT>vM  
        enableservice('AutomationServer') ?lbH02P{v  
    t~E<j+<2B  
    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 |\n@3cIK  
    -6tgsfEr  
    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: b B  x?  
    1. 在FRED脚本编辑界面找到参考. Xg=x7\V  
    2. 找到Matlab Automation Server Type Library uKz,SqX  
        3. 将名字改为MLAPP _* IPk  
         d~/q"r1"  
         %&->%U|'  
    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。 `+zWu 55;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :}h>by=  
    1. 创建Matlab服务器。 X=6y_^  
    2. 移动探测面对于前一聚焦面的位置。 !eAo  
    3. 在探测面追迹光线 L4b:F0  
    4. 在探测面计算照度 4-kZJ\]  
    5. 使用PutWorkspaceData发送照度数据到Matlab (]RM6i7  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 DNR~_3Aq  
    7. 用Matlab画出照度数据 kdxz!  
    8. 在Matlab计算照度平均值 6ns! ~g@  
    9. 返回数据到FRED中 [F_/2+e
