    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。 n[v`F  
    EL2z&  
    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: B=X_c5  
    enableservice('AutomationServer', true) Aq(,  
    enableservice('AutomationServer') &?y|Pn  
    h]|2b0  
    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 7<2?NLE8*

    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: %)^0NQv  
    1. 在FRED脚本编辑界面找到参考. ogdAJw6 9  
    2. 找到Matlab Automation Server Type Library G&M)n*o  
    3. 将名字改为MLAPP TC:t!:

    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。 ashVV~\8A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T0\[": A  
    1. 创建Matlab服务器。 0d`lugf  
    2. 移动探测面对于前一聚焦面的位置。 Lr"`OzDz  
    3. 在探测面追迹光线 1'k,P;s  
    4. 在探测面计算照度 (t,|FkVLV  
    5. 使用PutWorkspaceData发送照度数据到Matlab *iPBpEWC  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 IY(;:#l  
    7. 用Matlab画出照度数据 :ZM=P3QZ  
    8. 在Matlab计算照度平均值 UC00zW<Z@"  
    9. 返回数据到FRED中 Ye  >+
