    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。 S"Cz. bv  
    ?8V.iHJk  
    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: C.92FiC  
    enableservice('AutomationServer', true) ^r\ rpSN  
    enableservice('AutomationServer') I1E9E$m5\<  
    uPz+*4+  
    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 }UW7py!TN  
    %vJHr!x  
    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: }%jF!d  
    1. 在FRED脚本编辑界面找到参考. :jl*Y-mM  
    2. 找到Matlab Automation Server Type Library |q77  
    3. 将名字改为MLAPP J;0;oXwJ<

    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。 '9V/w[mI

    现在将脚本代码公布如下,此脚本执行如下几个步骤: PdcIHN  
    1. 创建Matlab服务器。 X,|8Wpi=  
    2. 移动探测面对于前一聚焦面的位置。 'c s(gc 0  
    3. 在探测面追迹光线 LlQsc{ Ddf  
    4. 在探测面计算照度 !2LX+*;  
    5. 使用PutWorkspaceData发送照度数据到Matlab :X;G]B .  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G68KoM  
    7. 用Matlab画出照度数据 te+}j7SU  
    8. 在Matlab计算照度平均值 n N<N~  
    9. 返回数据到FRED中 q9/v\~m
