    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。 V@8 4Cb  
    |VlAt#E  
    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: Fkz+Qz  
    enableservice('AutomationServer', true) =q^o6{d0"  
    enableservice('AutomationServer') C 1|e1  
    X`:(-3T  
    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 }`IN5NdYp  
    A`=ESz  
    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: q uv`~qn  
    1. 在FRED脚本编辑界面找到参考. R/b)hP ~  
    2. 找到Matlab Automation Server Type Library ).N}x^  
    3. 将名字改为MLAPP JQsS=m7Et

    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!UT&#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: mv SNKS  
    1. 创建Matlab服务器。 X+P& up06  
    2. 移动探测面对于前一聚焦面的位置。 (bH"x  
    3. 在探测面追迹光线 .-`7Av+7  
    4. 在探测面计算照度 b\][ x6zJp  
    5. 使用PutWorkspaceData发送照度数据到Matlab .+ai dWd  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 (~}yt.7K  
    7. 用Matlab画出照度数据 i{T0[\4  
    8. 在Matlab计算照度平均值 kdQ=%  
    9. 返回数据到FRED中 QCa$<~c
