    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。 e{Y8m Xu  
    t}Q PPp y  
    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: 6f'THU$  
    enableservice('AutomationServer', true) =Hd+KvA  
    enableservice('AutomationServer') # 0* oj/  
    r%uka5@  
    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 V* I2

    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: 2(i@\dZCb<  
    1. 在FRED脚本编辑界面找到参考. W2w A66MB  
    2. 找到Matlab Automation Server Type Library K ; e R)  
    3. 将名字改为MLAPP [uLpm*7

    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。 NI^jQS M]

    1. 创建Matlab服务器。 ">M:6\B  
    2. 移动探测面对于前一聚焦面的位置。 F&_b[xso7  
    3. 在探测面追迹光线 n8.Tag(#  
    4. 在探测面计算照度 .At^b4#(  
    5. 使用PutWorkspaceData发送照度数据到Matlab -Q MO*PY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6 k6}SlN[  
    7. 用Matlab画出照度数据 DX(!G a  
    8. 在Matlab计算照度平均值 3 +WmM4|
