    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。 %lmRe(M  
    N^N?!I  
    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: PyF4uCn"H  
    enableservice('AutomationServer', true) sn#h=,*4`  
    enableservice('AutomationServer') K),wAZI!7j  
    rT)R*3  
    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 ]~ M -KT  
    :W.(,65c  
    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: I\23as0q  
    1. 在FRED脚本编辑界面找到参考. SLo/7$rct  
    2. 找到Matlab Automation Server Type Library bm.H0rHR4  
    3. 将名字改为MLAPP LeCU"~

    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。 jwox?]f+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: A-$BB=Ot  
    1. 创建Matlab服务器。 e X@q'Zi  
    2. 移动探测面对于前一聚焦面的位置。 m`"s$\fah  
    3. 在探测面追迹光线 )O Cr6UR  
    4. 在探测面计算照度 0k 8SDRWU  
    5. 使用PutWorkspaceData发送照度数据到Matlab uBgHtjmae  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 GAlO<Mu  
    7. 用Matlab画出照度数据 Of=z!|l2  
    8. 在Matlab计算照度平均值 XN;eehB?aE
