    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。 (>5VS  
    F@(}=w^(A  
    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: 2WECQl=r  
    enableservice('AutomationServer', true) a=T7w;\h  
    enableservice('AutomationServer') P(i2bbU  
    0N[DV]  
    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 ~JRu MP  
    }br<2?y,  
    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: ]\mb6Hc  
    1. 在FRED脚本编辑界面找到参考. x^#{2}4u  
    2. 找到Matlab Automation Server Type Library LY cSMuJ  
    3. 将名字改为MLAPP _M4v1Hr48  
    =28H^rK{  
    |3lAye,t)a  
    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。 `L[32B9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T(Gf~0HYF  
    1. 创建Matlab服务器。 d*:qFq_  
    2. 移动探测面对于前一聚焦面的位置。 w,#W&>+&  
    3. 在探测面追迹光线 -V_S4|>   
    4. 在探测面计算照度 ]fS~N9B  
    5. 使用PutWorkspaceData发送照度数据到Matlab .lj!~_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <WKz,jh  
    7. 用Matlab画出照度数据 wQS w&G  
    8. 在Matlab计算照度平均值 >Pd23TsN  
    9. 返回数据到FRED中 [)6E) E`_e
