    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。 YrKWA  
    !Rt>xD  
    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: H7j0K~U0  
    enableservice('AutomationServer', true) !? gKqx'T$  
        enableservice('AutomationServer') /H==Hm/  
    GM<-&s!Uj  
    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 6JQ'Ik;$wX

    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: B93+BwN>95  
    1. 在FRED脚本编辑界面找到参考. K96<M);:g  
    2. 找到Matlab Automation Server Type Library l/awS!Q/nF  
        3. 将名字改为MLAPP 0K2`-mL

    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。 mdg i5v

    2. 移动探测面对于前一聚焦面的位置。 Ez=Olbk  
    3. 在探测面追迹光线 LE>]8[ f6S  
    4. 在探测面计算照度 ^ovR7+V  
    5. 使用PutWorkspaceData发送照度数据到Matlab aAA U{EWW  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ( ICd}  
    7. 用Matlab画出照度数据 ,WB{i^TD

    9. 返回数据到FRED中 5o8EC" 0
