    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。 i~};5j(  
    >9WJa5{  
    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: E{LLxGAEZ  
    enableservice('AutomationServer', true) fU6O:-  
    enableservice('AutomationServer') 1Q5:Vo^B#  
    u[{j;l(  
    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 &dH[lB  
    jOkc'  
    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: `u<\ 4&W  
    1. 在FRED脚本编辑界面找到参考. \ F\ /<  
    2. 找到Matlab Automation Server Type Library ~CtLSyB  
    3. 将名字改为MLAPP _u[2R=h  
    (6y[,lYH  
    }@)r\t4m  
    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。 (G>S`B

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <W>T!;4!  
    1. 创建Matlab服务器。 gwA+%]  
    2. 移动探测面对于前一聚焦面的位置。 EZ"n3#/  
    3. 在探测面追迹光线 3j I rB%  
    4. 在探测面计算照度 "jUM}@q5  
    5. 使用PutWorkspaceData发送照度数据到Matlab f:\)oIW9Kk  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -ho%9LW%|  
    7. 用Matlab画出照度数据 1*aO2dOq  
    8. 在Matlab计算照度平均值 a-cLy*W,~  
    9. 返回数据到FRED中 Daw;6f:
