    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。 (3)C_Z  
    \a{Aa  
    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: Q,[rrG;?@  
    enableservice('AutomationServer', true) , LCH2r  
    enableservice('AutomationServer') R1]v}f_I"  
    >:3xi{  
    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 p=:7 atE

    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: @C!JtgO%  
    1. 在FRED脚本编辑界面找到参考. YR$tPe  
    2. 找到Matlab Automation Server Type Library -0=}|$H.  
    3. 将名字改为MLAPP D<+ bzC

    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。 &. |;yt%v

    1. 创建Matlab服务器。 ~EM#Hc,  
    2. 移动探测面对于前一聚焦面的位置。 *Y| lO  
    3. 在探测面追迹光线 jUV#HT  
    4. 在探测面计算照度 Mq rt-VPh  
    5. 使用PutWorkspaceData发送照度数据到Matlab fJSV)\e0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 o+)m}'T8  
    7. 用Matlab画出照度数据 B`'}&6jr.
