Question

我有一个由矩阵表示的图像。让我们说它是21x23矩阵。

如何将矩阵分为10行和10列。但它们的大小不一定相同。

有一个函数mat2cell但我不知道如何使用它

Answer 1

让您的数据存储在inputmat中。

首先，您必须计算子矩阵的维数。例如，它们可能是：

SET ansi_nulls ON 
go 
SET quoted_identifier ON 
go 

ALTER PROCEDURE [dbo].[Slx_activity] 
AS 
    DECLARE @ReportStartDate DATETIME, 
            @ReportEndDate   DATETIME 
    DECLARE @Today DATETIME 

    SET @Today = Getdate() 

    DECLARE @Diff INT 

    SET @Diff = Datediff(day, Dateadd(day, 5, 0), @Today) 
    SET @ReportEndDate = Dateadd(day, @Diff - @Diff % 7, Dateadd(day, 5, 0)) 
    SET @ReportStartDate = Datediff(day, 6, @ReportEndDate) 

    IF Object_id('SLXActivity', 'U') IS NOT NULL 
      DROP TABLE slxactivity; 

    SELECT ' Current Activity:' + ' ' + p.[text] AS [TYPE], 
           h.createdate, 
           p.[text],

然后执行：

rows = diff(floor(linspace(0,21,11)))
cols = diff(floor(linspace(0,23,11)))

Matlab将图像分割为10x10个细胞
