    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。 tGdf/aTjy  
    M~*u;vA/  
    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: l=N2lHU  
    enableservice('AutomationServer', true) [ =x s4=  
    enableservice('AutomationServer') v4miU;|\  
    C${ S^v  
    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 Xb !MaNm)

    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: ZlYPoOq  
    1. 在FRED脚本编辑界面找到参考. r,goRK.  
    2. 找到Matlab Automation Server Type Library 7+TiyY]K  
    3. 将名字改为MLAPP [OTJVpC

    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。 )Dp/('Z2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: p47S^gW  
    1. 创建Matlab服务器。 %B 5r"=oO  
    2. 移动探测面对于前一聚焦面的位置。 cH-@V<  
    3. 在探测面追迹光线 'Djm0  
    4. 在探测面计算照度 ~1m2#>  
    5. 使用PutWorkspaceData发送照度数据到Matlab b?4/#&z]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 e6X[vc|Y}  
    7. 用Matlab画出照度数据 thO ~=RB
