    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。 M;R>]wP"V  
    ^Tx1y[hw$  
    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: FBsw\P5w  
    enableservice('AutomationServer', true) :|Cf$2k7  
    enableservice('AutomationServer') uHYI :(O  
    g=Lt 2UIJ  
    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 ^E^:=Q?'_  
    <>TBM^  
    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=1bGJ  
    1. 在FRED脚本编辑界面找到参考. Wj&s5;2a  
    2. 找到Matlab Automation Server Type Library .PgkHb=l@  
    3. 将名字改为MLAPP ;<\*(rUe

    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。 dq2v[? *R

    现在将脚本代码公布如下,此脚本执行如下几个步骤: S(pfd2^  
    1. 创建Matlab服务器。 y06 2/$*$  
    2. 移动探测面对于前一聚焦面的位置。 C;` fOCz^  
    3. 在探测面追迹光线 M%/D:0  
    4. 在探测面计算照度 ^^m%[$nw&r  
    5. 使用PutWorkspaceData发送照度数据到Matlab $1e@3mzM  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6x0>E^~  
    7. 用Matlab画出照度数据 j^gF~ Wz^  
    8. 在Matlab计算照度平均值 0^=S:~G  
    9. 返回数据到FRED中 ?k#% AM
