    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。 &3$z4df  
    nIoPC[%_  
    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: ;+tpvnV;]  
    enableservice('AutomationServer', true) ^.hoLwp.  
    enableservice('AutomationServer') X*,%&6O*  
    jWY$5Vq<H  
    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 Ma\Gb+>

    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: }Y*VAnY6;  
    1. 在FRED脚本编辑界面找到参考. i-'9AYyw  
    2. 找到Matlab Automation Server Type Library #~=hn8  
    3. 将名字改为MLAPP ph_4q@  
    EM/@T}

    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。 "d$m@c

    1. 创建Matlab服务器。 n f.wCtf].  
    2. 移动探测面对于前一聚焦面的位置。 v9D22,K-  
    3. 在探测面追迹光线 24/XNSE,-  
    4. 在探测面计算照度 fnNYX]_bk  
    5. 使用PutWorkspaceData发送照度数据到Matlab IZm(`b;t^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 jC3Vbm&ZZ  
    7. 用Matlab画出照度数据 ~\cO"(y5:O  
    8. 在Matlab计算照度平均值 g(Io/hyj  
    9. 返回数据到FRED中 ZWm8*}3]7_
