    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。 vSk1/  
    4!Lj\.!$  
    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: MgH O WoF  
    enableservice('AutomationServer', true) TU9$5l/;g  
    enableservice('AutomationServer') UhSaqq  
    gY_AO1  
    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 m21H68y  
    (>gb9n  
    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: Jv~^hN2  
    1. 在FRED脚本编辑界面找到参考. m4G))||9Q  
    2. 找到Matlab Automation Server Type Library >eX9dA3X  
    3. 将名字改为MLAPP HyIyrUrYW

    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。 H~W=#Cx

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ](z*t+">  
    1. 创建Matlab服务器。 _: !7M ^IU  
    2. 移动探测面对于前一聚焦面的位置。 Y5<W"[B!  
    3. 在探测面追迹光线 A#]78lR  
    4. 在探测面计算照度  `dIwBfg_  
    5. 使用PutWorkspaceData发送照度数据到Matlab @[]#[7  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 P-X2A2  
    7. 用Matlab画出照度数据 UFyk%#L  
    8. 在Matlab计算照度平均值 |^OK@KdL1  
    9. 返回数据到FRED中 Kae-Y
