    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。 V*giF`gq  
    @NLcO}  
    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: dHc\M|HCC  
    enableservice('AutomationServer', true) v'W{+>.  
    enableservice('AutomationServer') C^J<qq &  
    7Y5r3a}%  
    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 Y![Q1D!

    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: SMEl'y  
    1. 在FRED脚本编辑界面找到参考. wjA wJOw|  
    2. 找到Matlab Automation Server Type Library Eomfa:WL  
    3. 将名字改为MLAPP qjB:6Jq4q

    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。 sQJ\{'g

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0!hr9Y]Lx  
    1. 创建Matlab服务器。 V}jGxt0  
    2. 移动探测面对于前一聚焦面的位置。 I/O3OD  
    3. 在探测面追迹光线 `6Bx8CZ'I  
    4. 在探测面计算照度 >,e^}K}C  
    5. 使用PutWorkspaceData发送照度数据到Matlab PG&t~4QM`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 nip6|dN  
    7. 用Matlab画出照度数据 5,"c1[`-  
    8. 在Matlab计算照度平均值 RM;a]g*  
    9. 返回数据到FRED中 VOEV[?>ss
