    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。 zJ{?'kp  
    JA W}]:jC  
    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: 49f- u  
    enableservice('AutomationServer', true) H /Idc,*  
    enableservice('AutomationServer') Ol,;BZHc\  
    .qVz rS  
    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 gfE<XrG  
    Zgp]s+%E  
    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: mv@cGdxu  
    1. 在FRED脚本编辑界面找到参考. ?pgdj|"a  
    2. 找到Matlab Automation Server Type Library <hi@$.u_Q^  
    3. 将名字改为MLAPP *8}Y0V\s  
    nb(4"|8}  
    "|W .o=R  
    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。 3L/qU^`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: AH`n  
    1. 创建Matlab服务器。 QX (x6y>Q  
    2. 移动探测面对于前一聚焦面的位置。 KDwz!:ye  
    3. 在探测面追迹光线 ?fv?6r  
    4. 在探测面计算照度 f.V;Hl,  
    5. 使用PutWorkspaceData发送照度数据到Matlab MLg<YL  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 kN uDoo]z  
    7. 用Matlab画出照度数据 1|Y(XB^os(  
    8. 在Matlab计算照度平均值 fr'M)ox1  
    9. 返回数据到FRED中 I( BG%CO9
