    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。 jvQ*t_L  
    @-&s: Qli  
    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: l}lIi8  
    enableservice('AutomationServer', true) <bD>m[8,  
    enableservice('AutomationServer') NZ3/5%We/  
    eEn;!RS)  
    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 p+Y>F\r&w

    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: XZ5 /=z  
    1. 在FRED脚本编辑界面找到参考. uy}%0vLo  
    2. 找到Matlab Automation Server Type Library +tD[9b! m  
    3. 将名字改为MLAPP }@^4,FKJ

    ?Sb8@S&J  
    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。 ? mhs$g>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0p@k({]<  
    1. 创建Matlab服务器。 E.U_W  
    2. 移动探测面对于前一聚焦面的位置。 Q[d}J+l4{  
    3. 在探测面追迹光线 A.5i"Ci[ie  
    4. 在探测面计算照度 3ux0 Jr2yT  
    5. 使用PutWorkspaceData发送照度数据到Matlab c?%(Dp E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Dxk+P!!K  
    7. 用Matlab画出照度数据 ykFJ%sw3X  
    8. 在Matlab计算照度平均值 Z?O *'#yn  
    9. 返回数据到FRED中 6AWKLFMV
