    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。 yJ/m21f  
    z]gxkol\  
    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: nD MNaMYb  
    enableservice('AutomationServer', true) U%t:]6d&}  
    enableservice('AutomationServer') ~ W52Mbf  
    lU:z>gC  
    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 *yiJw\DRN

    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: [<1i[\^  
    1. 在FRED脚本编辑界面找到参考. p%xo@v(  
    2. 找到Matlab Automation Server Type Library dK|MQ <  
    3. 将名字改为MLAPP !`=r('l

    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。 :*0k:h6g

    1. 创建Matlab服务器。 >J.a, !  
    2. 移动探测面对于前一聚焦面的位置。 C]A*B  
    3. 在探测面追迹光线 K4,VSy1byI

    6. 使用PutFullMatrix发送标量场数据到Matlab中 zw\"!=r^  
    7. 用Matlab画出照度数据 ]9R?2{"K
