    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。 6tOi^+qN  
    =|y|P80w  
    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: - 8syjKTg  
    enableservice('AutomationServer', true) r`]7S_t5T  
    enableservice('AutomationServer') 9YSVK\2$  
    $e/*/.  
    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 N^B@3QF

    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: /!b x`cKG  
    1. 在FRED脚本编辑界面找到参考. L_*L`!vQA"  
    2. 找到Matlab Automation Server Type Library !b%,'fy)  
    3. 将名字改为MLAPP 11*"d#

    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。 *IlQ5+3I

    1. 创建Matlab服务器。 n.;3X  
    2. 移动探测面对于前一聚焦面的位置。 mcMb*?]  
    3. 在探测面追迹光线 |p'i,.(c_W
