    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。 E08!a  
    xE_~.EoB  
    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: rk+s[Qi~  
    enableservice('AutomationServer', true) q%s<y+  
    enableservice('AutomationServer') DbI)tDi5D  
    JWM4S4yZHR  
    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 (<`> B  
    "V:RKH`  
    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: , Sf:R4=  
    1. 在FRED脚本编辑界面找到参考. J{;\TNkJ  
    2. 找到Matlab Automation Server Type Library Ng&K5Z/  
    3. 将名字改为MLAPP L.9@rwfI

    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。 zcV~)go6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: UZJs!#P  
    1. 创建Matlab服务器。 mg3YKHNG  
    2. 移动探测面对于前一聚焦面的位置。 @ uL4'@Ej  
    3. 在探测面追迹光线 0 4ceDe  
    4. 在探测面计算照度 ],<pZ1V;  
    5. 使用PutWorkspaceData发送照度数据到Matlab lA,[&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 sEb*GF*.V  
    7. 用Matlab画出照度数据 IjPt JwW`A  
    8. 在Matlab计算照度平均值 c~Y  g(  
    9. 返回数据到FRED中 #3C] "
