    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。  snX5mD  
    xFgY#F  
    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: 'H97D-86/  
    enableservice('AutomationServer', true)  Qq>M}  
    enableservice('AutomationServer') v\&Wb_;A  
    @q|I$'K]x  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 iEnDS@7  
    y_QK _R<f  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: /-1[}h%U'  
    1. 在FRED脚本编辑界面找到参考. Td?a=yu:J  
    2. 找到Matlab Automation Server Type Library O9jqeF`L=  
    3. 将名字改为MLAPP {8'I+-  
    `O*+%/(  
    U#-89.x  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 >=$( ,8"

    现在将脚本代码公布如下,此脚本执行如下几个步骤: aO6w :IO  
    1. 创建Matlab服务器。 F`+}p-  
    2. 移动探测面对于前一聚焦面的位置。 d'q,:="c  
    3. 在探测面追迹光线 :Fu.S1j$  
    4. 在探测面计算照度 P6@(nGgK<  
    5. 使用PutWorkspaceData发送照度数据到Matlab $fL2w^ @  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Qn6'E  
    7. 用Matlab画出照度数据 SCZtHEl9  
    8. 在Matlab计算照度平均值 qE!.C}L +  
    9. 返回数据到FRED中 ^pIT,|myY7
