Question

我正在尝试获取数组每行的标签以实现RLE编码，其中标签的格式为[数组中的＃，行中重复的数字]。

我得到的数组最小为2x2，最大为10 x10。目的是要知道每行重复多少个数字，并得到上面解释的结果

我试图与for周期进行比较，但没有得到期望的结果并带有标志，但是我不能

matriz = randi([0,127],horizontal,vertical);
        set(handles.matriz,'String',num2str(matriz));
        for i= 1:horizontal
            cantidad = 0;
            for j = 1:vertical
                num = matriz (i,j);
                if(num == matriz(??))
                    contador = contador +1;
                end
                position = strcat('[',num2str(num),',''num2str(contador)',']');
            end
        end
        set(handles.bloques,'String',matriz_)

您所需的输出从您的帖子中不是很清楚。但是，我相信您有一个矩阵，并且您正在尝试计算逐行重复多少个矩阵元素。

我为您准备了以下代码，以了解如何逐元素遍历矩阵以比较行中的每个元素。

该代码非常不言自明。如果您仍然遇到麻烦，请不要犹豫。

（注意：有许多比下面的代码更有效的方法来执行此任务）。（注2：我的代码告诉您在输出语句中的一行中出现了多少个元素，您将在下面看到。如果只希望“重复”元素的数量，则从相应的结果中减去1。）

希望这会有所帮助。

function resultList = findRepeatingElementsRow()

matrix = randi(10,5);

numberOfRows = size(matrix, 1);
numberOfColumns = size(matrix, 2);

for i = 1:numberOfRows
    for j = 1:numberOfColumns
        matrixElement = matrix(i,j);
        counter = 0;
        for k = 1:numberOfColumns
            compareElement = matrix(i,k);
            if matrixElement == compareElement
                counter = counter + 1;
            end
        end
        msg = strcat('In row number', char(20), num2str(i), char(20), 'Matrix Element', char(20), num2str(matrixElement), char(20), 'is repeated', char(20), num2str(counter), char(20), 'time(s)');
        disp(msg);
    end
end

    10     6     2     1     8
     5     3     3     3     5
     2     7     4     9     6
     3     8     5     1     3
     5     3     6    10     5

In row number 1 Matrix Element 10 is repeated 1 time(s)
In row number 1 Matrix Element 6 is repeated 1 time(s)
In row number 1 Matrix Element 2 is repeated 1 time(s)
In row number 1 Matrix Element 1 is repeated 1 time(s)
In row number 1 Matrix Element 8 is repeated 1 time(s)
In row number 2 Matrix Element 5 is repeated 2 time(s)
In row number 2 Matrix Element 3 is repeated 3 time(s)
In row number 2 Matrix Element 3 is repeated 3 time(s)
In row number 2 Matrix Element 3 is repeated 3 time(s)
In row number 2 Matrix Element 5 is repeated 2 time(s)
In row number 3 Matrix Element 2 is repeated 1 time(s)
In row number 3 Matrix Element 7 is repeated 1 time(s)
In row number 3 Matrix Element 4 is repeated 1 time(s)
In row number 3 Matrix Element 9 is repeated 1 time(s)
In row number 3 Matrix Element 6 is repeated 1 time(s)
In row number 4 Matrix Element 3 is repeated 2 time(s)
In row number 4 Matrix Element 8 is repeated 1 time(s)
In row number 4 Matrix Element 5 is repeated 1 time(s)
In row number 4 Matrix Element 1 is repeated 1 time(s)
In row number 4 Matrix Element 3 is repeated 2 time(s)
In row number 5 Matrix Element 5 is repeated 2 time(s)
In row number 5 Matrix Element 3 is repeated 1 time(s)
In row number 5 Matrix Element 6 is repeated 1 time(s)
In row number 5 Matrix Element 10 is repeated 1 time(s)
In row number 5 Matrix Element 5 is repeated 2 time(s)

如何在同一行中重复的元素中搜索数组？
