    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。 Qvqqvk_tv  
    }iww:H-1  
    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: #kcSQ'  
    enableservice('AutomationServer', true) V3sL;  
    enableservice('AutomationServer') i[nF.I5*f  
    Qc"'8kt  
    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 IVjU`ij

    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: SF<Vds}A2  
    1. 在FRED脚本编辑界面找到参考. 8]"(!i_;)  
    2. 找到Matlab Automation Server Type Library )K]pnH|  
    3. 将名字改为MLAPP Q*ju sm

    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。 0b-?q&*_

    现在将脚本代码公布如下,此脚本执行如下几个步骤: mG2'Y)Sz  
    1. 创建Matlab服务器。 W>-B [5O&[  
    2. 移动探测面对于前一聚焦面的位置。 WFv!Pbq,  
    3. 在探测面追迹光线 I.jZ wW!r  
    4. 在探测面计算照度 eN>0wd5{L  
    5. 使用PutWorkspaceData发送照度数据到Matlab R: Z_g !h  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 jAhP> t:  
    7. 用Matlab画出照度数据 4^Rd{'mt  
    8. 在Matlab计算照度平均值 Y`ihi,s`H  
    9. 返回数据到FRED中 *75YGD
