    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。 UmP'L!  
    L7q |^`  
    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: #s"B-sWE  
    enableservice('AutomationServer', true) V/y=6wUiSl  
        enableservice('AutomationServer') T0 |H9>M  
    4,}GyVJFb`  
    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 "EPD2,%S  
    "DckwtG:%  
    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: y4F^|kS) [  
    1. 在FRED脚本编辑界面找到参考. j7/(sf  
    2. 找到Matlab Automation Server Type Library Eb@MfL  
        3. 将名字改为MLAPP lizTRVBE  
         n(&*kfk  
         4;<DJ.XlN=  
    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。 FBY ODw

    现在将脚本代码公布如下,此脚本执行如下几个步骤: o/JPYBhdl  
    1. 创建Matlab服务器。 rx:lKoOnB  
    2. 移动探测面对于前一聚焦面的位置。 :C%47qv  
    3. 在探测面追迹光线 I'IB_YRL4  
    4. 在探测面计算照度 7%CIt?Z%  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0j@IxEPs  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 T-P@u-DU  
    7. 用Matlab画出照度数据 3?ba 1F0Nw  
    8. 在Matlab计算照度平均值 2V$9ei6  
    9. 返回数据到FRED中 878tI3-
