    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。 za{z2# aJ  
    242dT/j  
    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: wcGI2aflD  
    enableservice('AutomationServer', true) ,M@LtA3g  
    enableservice('AutomationServer') qFEGV+  
    zO#{qF+~;  
    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 q;co53.+P)

    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: yU* upQ  
    1. 在FRED脚本编辑界面找到参考. |GPR3%9  
    2. 找到Matlab Automation Server Type Library QP/6N9/  
    3. 将名字改为MLAPP :B(F ?9qK  
    I,4t;4;Zk  
    u 6&<Bv  
    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。 m8KJ~02l#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: x1:#rb'  
    1. 创建Matlab服务器。 a^yBtb~,P  
    2. 移动探测面对于前一聚焦面的位置。 aq-`Bar  
    3. 在探测面追迹光线 F O"8B  
    4. 在探测面计算照度 jDI)iW`P  
    5. 使用PutWorkspaceData发送照度数据到Matlab Z4YQ5O5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 '[u=q -Lv  
    7. 用Matlab画出照度数据 sj;8[Xy's  
    8. 在Matlab计算照度平均值 Q `$Q(/  
    9. 返回数据到FRED中 aoNTRJ c$
