    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。 '4~I %Z7L  
    ?g@X+!RB  
    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: gPd ,  
    enableservice('AutomationServer', true) 7!Im|7Ty  
    enableservice('AutomationServer') })uyq_nz  
    ?/sn"~"  
    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 'BgR01w J  
    i7YUyU  
    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: f qWme:x  
    1. 在FRED脚本编辑界面找到参考. k_?OEkgUh  
    2. 找到Matlab Automation Server Type Library e!w2_6?3  
    3. 将名字改为MLAPP I|;zGmg#k  
    4JO 16  
    7o!t/WEEq  
    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。 .s41Tc5u

    现在将脚本代码公布如下,此脚本执行如下几个步骤: `}$bJCSF.n  
    1. 创建Matlab服务器。 aAn p7\7  
    2. 移动探测面对于前一聚焦面的位置。 Z:x`][vg  
    3. 在探测面追迹光线 x6Gl|e[jv  
    4. 在探测面计算照度 `0q=Z],  
    5. 使用PutWorkspaceData发送照度数据到Matlab w r,+9uK  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G6x'Myg I  
    7. 用Matlab画出照度数据 z?|bs?HKS  
    8. 在Matlab计算照度平均值 )g3c-W=  
    9. 返回数据到FRED中 P (Y\l
