    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。 p/l">d]+  
    UxF9Ko( ]d  
    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: lu+KfKa  
    enableservice('AutomationServer', true) Yi[MoYe/K  
    enableservice('AutomationServer') II=!E  
    4MzPm~Ct  
    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_o_M  
    /<-=1XJI  
    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: Ek_<2!%X  
    1. 在FRED脚本编辑界面找到参考. M^ e}w!U  
    2. 找到Matlab Automation Server Type Library @A`j Wao  
    3. 将名字改为MLAPP U KTfLh  
    Q`;eI a6U  
    KLu Og$i  
    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。 cf ^i!X0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: bI(8Um6m  
    1. 创建Matlab服务器。 gLFTnMO  
    2. 移动探测面对于前一聚焦面的位置。 LylCr{s7  
    3. 在探测面追迹光线 8\C][ y  
    4. 在探测面计算照度 <u],R.S)  
    5. 使用PutWorkspaceData发送照度数据到Matlab (c"!&&S^ =  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *5hbD-a:  
    7. 用Matlab画出照度数据 nz#eJ  
    8. 在Matlab计算照度平均值 y!rJ}e  
    9. 返回数据到FRED中 ?1O` Rd{tn
