    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。 7^<6|>j4  
    u.Tknw-X  
    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: ?JBA`,-  
    enableservice('AutomationServer', true) J,J6bfR/  
    enableservice('AutomationServer') {DZ xK(  
    9"zp>VR  
    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 *U- :2uf

    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: D!z'Y,.  
    1. 在FRED脚本编辑界面找到参考. 0 \V)DV.i  
    2. 找到Matlab Automation Server Type Library DFvGc`O4  
    3. 将名字改为MLAPP dDa&:L  
    t N4-<6  
    -Jt36|O  
    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。 'Y/kF1,*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: w c  
    1. 创建Matlab服务器。 fL*+[v4  
    2. 移动探测面对于前一聚焦面的位置。 ]D4lZK>H  
    3. 在探测面追迹光线 p`EgMzVO,  
    4. 在探测面计算照度 {yDQncq'^  
    5. 使用PutWorkspaceData发送照度数据到Matlab x~=Mn%Ew0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 11c\C Iu  
    7. 用Matlab画出照度数据 zB/VS_^^W:
