    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。 c%jsu"  
    BSOjyy1f  
    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: N4A&"1d&  
    enableservice('AutomationServer', true) V;H d)v( j  
    enableservice('AutomationServer') ^v ]UcnB0  
    Q^[e/U,  
    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 p "/(>8

    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: 2]2{&bu  
    1. 在FRED脚本编辑界面找到参考. LjSLg[i  
    2. 找到Matlab Automation Server Type Library qo)Q}0  
    3. 将名字改为MLAPP _yiR h:  
     V+peO  
    z~BD(FDI  
    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。 | A3U@>6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: txj wZ_p  
    1. 创建Matlab服务器。 ;R/k2^uF  
    2. 移动探测面对于前一聚焦面的位置。 W\&WS"=~  
    3. 在探测面追迹光线 dVPq%[J2  
    4. 在探测面计算照度 y>>vGU;  
    5. 使用PutWorkspaceData发送照度数据到Matlab fL(':W&n-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 i/5y^  
    7. 用Matlab画出照度数据 ay=KfY5  
    8. 在Matlab计算照度平均值 VV?]U$  
    9. 返回数据到FRED中 7fap*
