    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。 WynHcxC  
    3(6i6 vV  
    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:  {EZ ;  
    enableservice('AutomationServer', true) [*8w v^  
    enableservice('AutomationServer') )#i]exZ  
    Cl4y9|  
    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 g :e|  
    ;STO!^9~  
    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: N;RZIg(x  
    1. 在FRED脚本编辑界面找到参考. t`H^! b  
    2. 找到Matlab Automation Server Type Library 4$d|}ajH  
    3. 将名字改为MLAPP A CJmy2

    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。 t3v*P6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: EmG`ga)s  
    1. 创建Matlab服务器。 Mz+|~'R  
    2. 移动探测面对于前一聚焦面的位置。 +z;xl-*[  
    3. 在探测面追迹光线 `=b*g24z[N  
    4. 在探测面计算照度 Yca9G?^\v  
    5. 使用PutWorkspaceData发送照度数据到Matlab W{ @lt}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ANp4yy+  
    7. 用Matlab画出照度数据 09%q/-$  
    8. 在Matlab计算照度平均值 W&BwBp]K  
    9. 返回数据到FRED中 kH1l -mxz
