    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。 M4m$\~zf  
    8VQ 24r  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: H'=(`  
    enableservice('AutomationServer', true) l=}~v  
        enableservice('AutomationServer') p$E8Bn%[  
    lfN~A"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 v [njdP  
    ][;G=oCT  
    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: RA O`i>@  
    1. 在FRED脚本编辑界面找到参考. 9z>z3,ftN  
    2. 找到Matlab Automation Server Type Library ]N{0:Va@D  
        3. 将名字改为MLAPP > \Sr{p5KR  
         ve6w<3D@  
         NbRn*nb/T  
    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。 nBItO~l

        6. 使用PutFullMatrix发送标量场数据到Matlab中 tBATZ0nK`Q  
    7. 用Matlab画出照度数据 I=DxRgt  
    8. 在Matlab计算照度平均值 zj{r^D$  
    9. 返回数据到FRED中 XT>.`, sv
