    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。 q g2 fTe  
    9-/u _$  
    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(3n v[  
    enableservice('AutomationServer', true) d/&W[jJ  
    enableservice('AutomationServer') +x!Hc  
    Wg5<@=x!G  
    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 ']bw37_U,  
    0#G@F5; <  
    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: @1w[~QlV  
    1. 在FRED脚本编辑界面找到参考. A4~- {.w=  
    2. 找到Matlab Automation Server Type Library ?<;9=l\Q  
    3. 将名字改为MLAPP &xWej2a!

    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。 C ^IPddw>

    2. 移动探测面对于前一聚焦面的位置。 .vnQZ*6  
    3. 在探测面追迹光线 En9>onJ  
    4. 在探测面计算照度 P @Jo[J<  
    5. 使用PutWorkspaceData发送照度数据到Matlab $ucDz f=o  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 wi/qI(O!  
    7. 用Matlab画出照度数据 3<x1s2U
