    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。 DtyT8kr  
    yU&A[DZQ  
    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: |(Io(e  
    enableservice('AutomationServer', true) BYP,}yzA  
    enableservice('AutomationServer') *9*6n\~aI  
    -H{c@hl  
    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 m&b!\"0

    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: vBq 2JJAl  
    1. 在FRED脚本编辑界面找到参考. o KX!{  
    2. 找到Matlab Automation Server Type Library ( ]'4_~e  
    3. 将名字改为MLAPP zaR~fO  
    j @sd x)1+  
    IN),Lu0K  
    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。 kVZ>Dc2M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fytgS(?I'  
    1. 创建Matlab服务器。 4LKOBiEM  
    2. 移动探测面对于前一聚焦面的位置。 RVX-3FvP  
    3. 在探测面追迹光线 dAohj QH:  
    4. 在探测面计算照度 N!^U{;X7/  
    5. 使用PutWorkspaceData发送照度数据到Matlab %q(n'^#Z.y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Qq^>7OU>Co  
    7. 用Matlab画出照度数据 866n{lyL  
    8. 在Matlab计算照度平均值 M {_`X  
    9. 返回数据到FRED中 : !J!l u
