Question

write a function that return a list of row numbers in matrix with removing the wrong value.

Ex: remove_row( matrix, wro)

if matrix = [[5,2,8],[6,7,20],[10,25,9]] wro= 20 then output will be [1,2]

Do not use any built in functions.

Answer 1

matrix = [5,2,8;6,7,20;10,25,9]
wro = 20
function output = remove_row(matrix, wro)
    n_rows = size(matrix, 1)
    n_cols = size(matrix, 2)
    output = []
    count = 0
    for r = 1:n_rows
        flag = 0
        for c = 1:n_cols
            if(matrix(r,c) == wro)
                flag = 1
            end
        end
        if(flag == 0)
            count = count + 1
            output = [output count]
        end
    end
end
remove_row(matrix, wro)
