    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。 7l8[xV  
    ;#?M)o:q  
    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:  |qcD;  
    enableservice('AutomationServer', true) sOFa!bdPW  
    enableservice('AutomationServer') Rz <OF^Iy  
    V*n==Nb5L  
    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 s PYX~G&T

    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: %Tcf6cK"  
    1. 在FRED脚本编辑界面找到参考. @9 8;VWY\  
    2. 找到Matlab Automation Server Type Library =6%|?5G  
    3. 将名字改为MLAPP 54p tP

    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。 X33v:9=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: tiQ;#p7%  
    1. 创建Matlab服务器。 Rph%*~'  
    2. 移动探测面对于前一聚焦面的位置。 nnCug  
    3. 在探测面追迹光线 ma8wmQ9JR  
    4. 在探测面计算照度 =v-2@=NJ`K  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^[# & ^[-V  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 y%(X+E"n*  
    7. 用Matlab画出照度数据 : iCM=k  
    8. 在Matlab计算照度平均值 &~~s6   
    9. 返回数据到FRED中 !e8i/!}^S
