    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。 @O'NJh{D`  
    f~\H|E8(  
    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: poW%Fzj  
    enableservice('AutomationServer', true) g[1>|Ax`'  
    enableservice('AutomationServer') mY/"rm  
    o*/;Zp==  
    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 CN ( :  
    9/e>%1.  
    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: M0xhcU_  
    1. 在FRED脚本编辑界面找到参考. p*42 @1,  
    2. 找到Matlab Automation Server Type Library wU!-sf;]y  
    3. 将名字改为MLAPP @@K/0:],

    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。 xBc|rqge

    现在将脚本代码公布如下,此脚本执行如下几个步骤: mOh?cjOi  
    1. 创建Matlab服务器。 R|(X_A  
    2. 移动探测面对于前一聚焦面的位置。 aV|V C $  
    3. 在探测面追迹光线 OYt_i'Q  
    4. 在探测面计算照度 \RR` F .7  
    5. 使用PutWorkspaceData发送照度数据到Matlab K/Yeh<_&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 qx1Js3%  
    7. 用Matlab画出照度数据 5j.@)XXe  
    8. 在Matlab计算照度平均值 UakVmVN/P  
    9. 返回数据到FRED中 qOy(dG g
