删除矩阵元素完全相同的行

函数：

function X2=row_same(X1)
 
[m,~] = size(X1);
    
row_to_delete = [];

    for i = 1:m

        if max(X1(i,:)) - min(X1(i,:)) == 0

        % 依次将需要删除的行数保存到该向量中
        row_to_delete = [row_to_delete;i];
   
        end
    end

for t = 1:length(row_to_delete)
    X1(row_to_delete(t),:) = []; 

X2 = X1;

end

end

效果：

将第二行（全是1）删除

删除矩阵元素完全相同的列

函数：

function X2 = columns_same(X1)

[~,n] = size(X1);

row_to_delete = [];

    for i = 1:n

        if max(X1(:,i)) - min(X1(:,i)) == 0

        % 依次将需要删除的行数保存到该向量中
        row_to_delete = [row_to_delete;i];
        
        end
    end

for t = 1:length(row_to_delete)
    X1(:,row_to_delete(t)) = []; 

X2 = X1;

end

end

效果：

将第二列（全是1）删除
