    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。 <o\I C?A  
    TfqQh!Y  
    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: ,(CIcDJ2U_  
    enableservice('AutomationServer', true) fmq9u(!R  
    enableservice('AutomationServer') _cH 7lO[  
    8Dy;'BtT  
    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 W%cJ#R[o  
    <f`G@  
    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: giz#(61j^  
    1. 在FRED脚本编辑界面找到参考. |0/~7l  
    2. 找到Matlab Automation Server Type Library khtSZ"8X  
    3. 将名字改为MLAPP +eD+Z.{

    [!#<nY/C  
    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。 ;-X5#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: o Kfm=TbY  
    1. 创建Matlab服务器。 `V[{,!l;X

    4. 在探测面计算照度 u DpCW}  
    5. 使用PutWorkspaceData发送照度数据到Matlab d% :   
    6. 使用PutFullMatrix发送标量场数据到Matlab中 * "Z5bKL  
    7. 用Matlab画出照度数据 <)\  
    8. 在Matlab计算照度平均值 ^5 sO;vf  
    9. 返回数据到FRED中 B#K{Y$!v
