    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。 J7C?Z  
    v=+3AW-|v  
    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:  I{ki))F  
    enableservice('AutomationServer', true) ^^*L;b>I  
    enableservice('AutomationServer') Q'!'+;&%  
    s;E(51V<>  
    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 1 0.Z Bfn  
    fI2 y(p{?  
    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%G[Y^^,  
    1. 在FRED脚本编辑界面找到参考. ya5HAs  
    2. 找到Matlab Automation Server Type Library Yk)fBPHr  
    3. 将名字改为MLAPP MxUbx+_N  
    "KS" [i!3j  
    Dgc6rv#  
    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。 "EA =auN{

    现在将脚本代码公布如下,此脚本执行如下几个步骤: jJNl{nyq  
    1. 创建Matlab服务器。 O!hp=`B,jf  
    2. 移动探测面对于前一聚焦面的位置。 n/ :#:  
    3. 在探测面追迹光线 {Rb;1 eYj  
    4. 在探测面计算照度 N6p0`  
    5. 使用PutWorkspaceData发送照度数据到Matlab e==/+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 EkRx/  
    7. 用Matlab画出照度数据 Q4*{+$A  
    8. 在Matlab计算照度平均值 %Tu(>vnuj  
    9. 返回数据到FRED中 Y:#B0FD,gC
