    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。 puOC60zI  
    pgT9hle/  
    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: 1%%'6cWWu  
    enableservice('AutomationServer', true) {jjSJIV1  
    enableservice('AutomationServer') 0axxQ!Ivx  
    ^$!987"  
    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 + :Vrip  
    !BDUv(  
    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: wu A^'T  
    1. 在FRED脚本编辑界面找到参考. - a y5  
    2. 找到Matlab Automation Server Type Library @}WNKS&m  
    3. 将名字改为MLAPP MU'@2c

    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。 x[QZ@rGIW

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h35Hu_c&  
    1. 创建Matlab服务器。 @9Q2$  
    2. 移动探测面对于前一聚焦面的位置。 v!H:^!z  
    3. 在探测面追迹光线 Cs wE  
    4. 在探测面计算照度 %a];  
    5. 使用PutWorkspaceData发送照度数据到Matlab $6T3y8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 FW8-'~  
    7. 用Matlab画出照度数据 3J{vt"dS  
    8. 在Matlab计算照度平均值 ,w{m3;]_%  
    9. 返回数据到FRED中 1j0-9Kg'
