    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。 `F1 ( v  
    Fh$Xcz~i  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: jR&AQ-H&  
    enableservice('AutomationServer', true) v:$Y |mh  
    enableservice('AutomationServer') awa$o  
    EJ3R{^  
    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 !ZlNPPrq}

    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: c\pPwG  
    1. 在FRED脚本编辑界面找到参考. .EUOKPK4W  
    2. 找到Matlab Automation Server Type Library S}cm.,/w  
    3. 将名字改为MLAPP i&?do{YQ)  
    .J3Dk=/  
    h47l;`kD-#  
    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。 *n %J#[e(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: u)fmXoQ  
    1. 创建Matlab服务器。 e RjpR?!\  
    2. 移动探测面对于前一聚焦面的位置。 W=EvEx^?%  
    3. 在探测面追迹光线 ul$YV9 [\  
    4. 在探测面计算照度 ]n:)W.|`R  
    5. 使用PutWorkspaceData发送照度数据到Matlab DOm5azO!>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 V OViOD  
    7. 用Matlab画出照度数据 ~IKPi==@,  
    8. 在Matlab计算照度平均值 hOSkxdi*^  
    9. 返回数据到FRED中 K}U}h>N
