    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>0a?=1[  
    D hN{Y8'~  
    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: ,8=`Y9#  
    enableservice('AutomationServer', true) ]!@z3Hv3  
    enableservice('AutomationServer') criQa<N"  
    N4]Sp v  
    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 6j*L]S c

    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: <OX_6d*@  
    1. 在FRED脚本编辑界面找到参考. ZGILV  
    2. 找到Matlab Automation Server Type Library YkOl@l$D  
    3. 将名字改为MLAPP R,+Pcn$ws  
    qDG{hvl[1r  
    gLm ]*  
    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。 T0:%,o

    现在将脚本代码公布如下,此脚本执行如下几个步骤: A_h|f5  
    1. 创建Matlab服务器。 2O|jVGap5x  
    2. 移动探测面对于前一聚焦面的位置。 {RG4m{#9  
    3. 在探测面追迹光线 `S`,H  
    4. 在探测面计算照度 Ijg //=  
    5. 使用PutWorkspaceData发送照度数据到Matlab , %8keGhl  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8i epG  
    7. 用Matlab画出照度数据 ^{<!pvT  
    8. 在Matlab计算照度平均值 prIPPeMdz  
    9. 返回数据到FRED中 A_8UPGh8
