    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。 0 pH qNlb  
    qxsK-8KT<  
    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: 6uYCU|JsU  
    enableservice('AutomationServer', true) q=5#t~?  
    enableservice('AutomationServer') y#3mc#)k  
    &\$l%icuo  
    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 ~5HI9A4^  
    k@eU #c5c  
    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: Mlp[xk|  
    1. 在FRED脚本编辑界面找到参考. *FkG32k  
    2. 找到Matlab Automation Server Type Library F(8>"(C  
    3. 将名字改为MLAPP p*rBT,'

    ! Q`GA<ikv  
    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。 h,q%MZ==^s

    现在将脚本代码公布如下,此脚本执行如下几个步骤: d FF[2  
    1. 创建Matlab服务器。 h'x|yy]@3  
    2. 移动探测面对于前一聚焦面的位置。 P+sxlf:0  
    3. 在探测面追迹光线 J3fcnI  
    4. 在探测面计算照度 H[guJ)4#@  
    5. 使用PutWorkspaceData发送照度数据到Matlab DYU+?[J  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 J 21D/#v  
    7. 用Matlab画出照度数据 nBGFa  
    8. 在Matlab计算照度平均值 .N99=%[}h  
    9. 返回数据到FRED中 xn&G`
