    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。 dvk? A$  
    AyKaazm]9  
    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: a2*WZc`  
    enableservice('AutomationServer', true) Xz0jjO,  
    enableservice('AutomationServer') U%ce0z  
    W 0Q-&4  
    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 y5.Z<Y  
    mk1;22o{TX  
    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: &eT)c<yhyK  
    1. 在FRED脚本编辑界面找到参考. vt[4"eU  
    2. 找到Matlab Automation Server Type Library _`L,}=um'  
    3. 将名字改为MLAPP uYS?# g  
    r:y *l4  
    =V1k'XJ  
    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。 Rs:<'A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *~fZ9EkD  
    1. 创建Matlab服务器。 %FQMB  
    2. 移动探测面对于前一聚焦面的位置。 >/EmC3?b!  
    3. 在探测面追迹光线 /g712\?M4  
    4. 在探测面计算照度 'bkecC  
    5. 使用PutWorkspaceData发送照度数据到Matlab L._I"g5 H9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7[QU *1bk  
    7. 用Matlab画出照度数据 er^z:1'  
    8. 在Matlab计算照度平均值 >\8Bu#&s4  
    9. 返回数据到FRED中 J}TS-j0
