    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。 }BiA@n,  
    |%j7Es  
    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: uf`/-jY  
    enableservice('AutomationServer', true) "F?p Y@4  
    enableservice('AutomationServer') ]T%wRd5&-  
    *a` _,Q{x  
    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 *7C l1o  
    LHs^Xo18  
    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: |^O3~!JP(>  
    1. 在FRED脚本编辑界面找到参考. hYVy65Ea  
    2. 找到Matlab Automation Server Type Library zI_pP?4;.q  
    3. 将名字改为MLAPP T/q*k)IoR

    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。 JiGS[tR

    2. 移动探测面对于前一聚焦面的位置。 7/bF0 4~%  
    3. 在探测面追迹光线 c/,B?  
    4. 在探测面计算照度 1+Bj` ACP  
    5. 使用PutWorkspaceData发送照度数据到Matlab g?>   
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #3YYE5cB  
    7. 用Matlab画出照度数据 p9eTrFDy?  
    8. 在Matlab计算照度平均值 cB2~W%H  
    9. 返回数据到FRED中 >"D0vj
