    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。 $~3?nib"j  
    5'<J@3B  
    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: ;W 3#q:  
    enableservice('AutomationServer', true) Wq2 Bo*[*  
    enableservice('AutomationServer') C1`fJh y  
    5)c B\N1u  
    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 gB_gjn\

    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: xe4`D>LUo  
    1. 在FRED脚本编辑界面找到参考. u+;iR/  
    2. 找到Matlab Automation Server Type Library Nf5zQ@o_y  
    3. 将名字改为MLAPP X :#}E7]j

    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。 +xL' LC x

    现在将脚本代码公布如下,此脚本执行如下几个步骤: H2S/!Q;K  
    1. 创建Matlab服务器。 ]>/oo=E  
    2. 移动探测面对于前一聚焦面的位置。 Fy*t[>  
    3. 在探测面追迹光线 6fm oI K{  
    4. 在探测面计算照度 :@b=;  
    5. 使用PutWorkspaceData发送照度数据到Matlab h1~/zM/`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 eemC;JV%  
    7. 用Matlab画出照度数据 v8"Zru  
    8. 在Matlab计算照度平均值 r0Zj'F_e  
    9. 返回数据到FRED中 < ZG!w^
