    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。 55\mQ|.Jn  
    ARo5 Ss{  
    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: tTt~W5lo  
    enableservice('AutomationServer', true) -GjJrYOU  
    enableservice('AutomationServer') t T:yvU@a  
    Mr(3]EfgO  
    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 2T9Z{v

    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: eo[^ij  
    1. 在FRED脚本编辑界面找到参考. ] fB{  
    2. 找到Matlab Automation Server Type Library iI7~9SCE  
    3. 将名字改为MLAPP VCO/s9AL

    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。 N%+M+zEJ

    1. 创建Matlab服务器。 {{\HU0g>&  
    2. 移动探测面对于前一聚焦面的位置。 aT#|mk=\  
    3. 在探测面追迹光线 6~LpBlb  
    4. 在探测面计算照度 W!*vO>^1W  
    5. 使用PutWorkspaceData发送照度数据到Matlab yk/XfwQ5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "5K: "m  
    7. 用Matlab画出照度数据 r^)<Jy0|r
