    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。 |ENh)M8}r  
    hpk7 A np  
    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: +ck}l2&#  
    enableservice('AutomationServer', true) ;A[Q2(w+  
    enableservice('AutomationServer') |Q>IrT  
    *{{89E>wC  
    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 :BT q!>s  
    teVM*-  
    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: zdH kG_PT  
    1. 在FRED脚本编辑界面找到参考. k VQ\1!  
    2. 找到Matlab Automation Server Type Library D1;QC  
    3. 将名字改为MLAPP L/^I*p,  
    xId.GWY1  
    Y6d@h? ht  
    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。 I<tm"?q0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: t |oR7qa{w  
    1. 创建Matlab服务器。 ;*&-C9b  
    2. 移动探测面对于前一聚焦面的位置。 po7qmLq  
    3. 在探测面追迹光线 Q NVa?'0"Y  
    4. 在探测面计算照度 Sa5G.^ XI  
    5. 使用PutWorkspaceData发送照度数据到Matlab @\I#^X5lv  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 t0 ?\l)  
    7. 用Matlab画出照度数据 5/z/>D;  
    8. 在Matlab计算照度平均值 )sp+8  
    9. 返回数据到FRED中 G*v,GR
