    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。 \$Y Kw0K  
    !s pp*Q)#\  
    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: Aifc0P-H  
    enableservice('AutomationServer', true) M*FUtu  
    enableservice('AutomationServer') sS;6QkI"y  
    ,#[0As29u  
    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 j_*$ Avy

    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: nf& P Dv1  
    1. 在FRED脚本编辑界面找到参考. OJiW@Z_\  
    2. 找到Matlab Automation Server Type Library c7 Sa|9*dR  
    3. 将名字改为MLAPP > nV~5f+

    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。 y\K r@;q0w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >p#`%S  
    1. 创建Matlab服务器。 eqbQ,, &  
    2. 移动探测面对于前一聚焦面的位置。 \MBbZB9@  
    3. 在探测面追迹光线 bA}9He1  
    4. 在探测面计算照度 g^|}e?  
    5. 使用PutWorkspaceData发送照度数据到Matlab H'k$<S  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 d%_=r." Y  
    7. 用Matlab画出照度数据 #\s*>Z  
    8. 在Matlab计算照度平均值 C'&)""3d  
    9. 返回数据到FRED中 VuA7rIF$66
