    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/N{~  
    NY3/mS3w  
    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: @Rw]boC  
    enableservice('AutomationServer', true) ]kir@NMv>  
        enableservice('AutomationServer') th^&wp  
    DedY(JOvB  
    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 PNB E  
    BCI[jfd7  
    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: 2EC<8}CG  
    1. 在FRED脚本编辑界面找到参考. ([ODmZHv  
    2. 找到Matlab Automation Server Type Library G6XDPr:}  
        3. 将名字改为MLAPP 2]V&]s8Wi=

         v\G+t2{  
    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。 0..]c-V(G

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *3A)s O  
    1. 创建Matlab服务器。 H$k2S5,,z  
    2. 移动探测面对于前一聚焦面的位置。 l_i&8*=Px  
    3. 在探测面追迹光线 L(q~%  
    4. 在探测面计算照度 '&!:5R59  
    5. 使用PutWorkspaceData发送照度数据到Matlab mIW/x/I  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 aflBDo1c  
    7. 用Matlab画出照度数据 $2>"2*,04  
    8. 在Matlab计算照度平均值 il[waUfmD  
    9. 返回数据到FRED中 *q*$%H
