    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。 aUk]wiwIR9  
    Z ygu/M 6  
    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: lc\{47LwZ  
    enableservice('AutomationServer', true) o[)*Y`xq<w  
    enableservice('AutomationServer') 4 (XV)QR  
    PUmgcMt  
    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 eY[kUMo  
    F-Bj  
    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: b3Q k;yz  
    1. 在FRED脚本编辑界面找到参考. \03ZE^H  
    2. 找到Matlab Automation Server Type Library |u]IOw&1  
    3. 将名字改为MLAPP *vzEfmN:d  
    '0w</g  
    3~1Gts  
    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。 8]D0)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {gh<SZsE  
    1. 创建Matlab服务器。 9yz@hdG  
    2. 移动探测面对于前一聚焦面的位置。 r @}N6U~*  
    3. 在探测面追迹光线 S)?N6sz%  
    4. 在探测面计算照度 C8x9 Jrc  
    5. 使用PutWorkspaceData发送照度数据到Matlab z69u@  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vi28u xc  
    7. 用Matlab画出照度数据 nyetK  
    8. 在Matlab计算照度平均值 [* M':  
    9. 返回数据到FRED中 YSrjg|k*
