    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。 3w+ +F@(  
    J!yK/*sO,  
    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: 1vCVTuRF  
    enableservice('AutomationServer', true) uC2qP)m,^  
    enableservice('AutomationServer') i1!Y {  
    0bjZwC4J  
    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 +[pJr-k

    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: wYh]3  
    1. 在FRED脚本编辑界面找到参考. Kj:'Ei7  
    2. 找到Matlab Automation Server Type Library 4hW:c0  
    3. 将名字改为MLAPP . Fm| $x  
    aUKa+"`S  
    'r} y{`3M  
    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。 +B4i,]lCx

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \4uj!LgTb  
    1. 创建Matlab服务器。 hO(A_Bw  
    2. 移动探测面对于前一聚焦面的位置。 QG09=GQ  
    3. 在探测面追迹光线 cpx:4R,  
    4. 在探测面计算照度 zvT8r(<n}  
    5. 使用PutWorkspaceData发送照度数据到Matlab !iUT Re  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 cK'}+  
    7. 用Matlab画出照度数据 R%Xz3Z&|  
    8. 在Matlab计算照度平均值 o>I,$=  
    9. 返回数据到FRED中 th+LScOX
