    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。 add-]2`  
    =@>&kU%$&  
    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: a\MJbBXv  
    enableservice('AutomationServer', true) w5Xdq_e3  
    enableservice('AutomationServer') t {}1 f  
    4r*6fJ*bJ  
    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 O"Q=66.CR  
    &#l M$7/  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: OH w6#N$\  
    1. 在FRED脚本编辑界面找到参考. xj<SnrrC]u  
    2. 找到Matlab Automation Server Type Library w[&BY  
    3. 将名字改为MLAPP VbYapPu4b!

    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。 t JP(eaqZ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3^Y-P8.zdB  
    1. 创建Matlab服务器。 QZfnoKz  
    2. 移动探测面对于前一聚焦面的位置。 ~cjvo?)&e;  
    3. 在探测面追迹光线 eu =2a>  
    4. 在探测面计算照度 Tp7?:YY|  
    5. 使用PutWorkspaceData发送照度数据到Matlab r[x7?cXsW  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 DH%X+r  
    7. 用Matlab画出照度数据 sMx\WTyz  
    8. 在Matlab计算照度平均值 JY,+eD  
    9. 返回数据到FRED中 !IS ,[
