    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。 ',Z]w;D!G  
    n[;)(  
    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: #$ka.Pj  
    enableservice('AutomationServer', true) $? Z}hU  
    enableservice('AutomationServer') jU 3ceXV  
    \ %xku:  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 > B;YYj~f}  
    ]#S<]vA  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Fv(FRZ)  
    1. 在FRED脚本编辑界面找到参考. :rk6Stn$z  
    2. 找到Matlab Automation Server Type Library E>|fbaN-%  
    3. 将名字改为MLAPP ]"O* &

    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。 UZ-pN_!Z:

    现在将脚本代码公布如下,此脚本执行如下几个步骤: P=P']\`p+  
    1. 创建Matlab服务器。 .f[z_% ar  
    2. 移动探测面对于前一聚焦面的位置。 Rw63{b/  
    3. 在探测面追迹光线 h`vT[u~l  
    4. 在探测面计算照度 #l*w=D?  
    5. 使用PutWorkspaceData发送照度数据到Matlab c[3x>f0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [Ak 0kH >  
    7. 用Matlab画出照度数据 C%%gCPI^y  
    8. 在Matlab计算照度平均值 i}f"'KW  
    9. 返回数据到FRED中 3C;;z
