    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。 h^ Cm\V  
    ~LS</_N  
    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: C][$0  
    enableservice('AutomationServer', true) j,.M!q]  
        enableservice('AutomationServer') +;~N; BT  
    F-s{#V1=  
    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 DKj iooD

    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: @%,~5{Ir  
    1. 在FRED脚本编辑界面找到参考. v":q_w<k  
    2. 找到Matlab Automation Server Type Library :GIBB=D9  
        3. 将名字改为MLAPP _z#" BN  
         <G}Lc  
         KM;H '~PZi  
    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。 P\MDD@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: d}Pfj=W  
    1. 创建Matlab服务器。 DP @1to@  
    2. 移动探测面对于前一聚焦面的位置。 :xr^E]  
    3. 在探测面追迹光线 7*PBJt\  
    4. 在探测面计算照度 jkL=JAcf~  
    5. 使用PutWorkspaceData发送照度数据到Matlab *<sc[..)  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 K80f_ iT 5  
    7. 用Matlab画出照度数据 zu1"`K3b  
    8. 在Matlab计算照度平均值 -W9DH^EL<  
    9. 返回数据到FRED中 D U\ytD`u
