    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。 G9^`cTvv'8  
    _\X ,a5Un  
    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: /HLI9  
    enableservice('AutomationServer', true) *lvADW5e  
    enableservice('AutomationServer') uAeo&|&  
    dhob]8b  
    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 Hvm}@3F|  
    %rG4X  
    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: rL1yq|]I  
    1. 在FRED脚本编辑界面找到参考. Sp5:R75vI  
    2. 找到Matlab Automation Server Type Library N'VTdf?  
    3. 将名字改为MLAPP 6wh PW .

    'wk,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。 K<*6E@+i

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |-}. Y(y  
    1. 创建Matlab服务器。 o13jd NQ-  
    2. 移动探测面对于前一聚焦面的位置。 8F8?1  
    3. 在探测面追迹光线 B1)Eo2i#  
    4. 在探测面计算照度 yO1 7C  
    5. 使用PutWorkspaceData发送照度数据到Matlab dgpE3 37Lt  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 49Jnp>h  
    7. 用Matlab画出照度数据 y|ZL< L  
    8. 在Matlab计算照度平均值 :TU|:2+  
    9. 返回数据到FRED中 dYrgL3'
