    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。 6>)]7(B<d  
    3_2(L"S2  
    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: >De\2gbJ  
    enableservice('AutomationServer', true) o_p//S#q  
    enableservice('AutomationServer') e@s+]a8D-k  
    2>#Pt^R:C  
    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 |<\L B

    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: @c{=:kg5  
    1. 在FRED脚本编辑界面找到参考. o(w1!spA  
    2. 找到Matlab Automation Server Type Library ~wIVw}  
    3. 将名字改为MLAPP ZGa>^k[:  
    O,ZvV3  
    t<9oEjk["  
    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。 b&A+`d

    1. 创建Matlab服务器。 FGBPhH% (8  
    2. 移动探测面对于前一聚焦面的位置。 u#?K/sU  
    3. 在探测面追迹光线 y@'8vOh`  
    4. 在探测面计算照度 za'Eom-<u  
    5. 使用PutWorkspaceData发送照度数据到Matlab <0vQHND,3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [a\:K2*'
