project_4

function [matrix, Min_matrix,Max_matrix,Sum,Tmatrix,multi_matrix] = project4(m,n,Min,Max)
m = input('ammount of rows in the matrix: ');
n = input('amount of columns in the matrix: ');
Max = input('highest nr in your matrix: ');
Min = input('lowest nr in your matrix: ');

% first Question: Create your Matrix
matrix = randi( [Min Max], m , n )

% 2nd Question: The addition of all the matrix´s numbers
% Hand typed: sum(sum(ans))
Sum = sum(sum(matrix))

%3rd Question: Transpose and multiply your matrix
% Hand typed: transpose(ans)
Tmatrix = transpose(matrix)
multi_matrix = Tmatrix * matrix

%4th Question:  Find the Minimum and Maximum nr in matrix
% Hand typed: max(max(ans)) and min(min(ans))
Min_matrix = min(min(matrix))
Max_matrix = max(max(matrix))

% %5th: rewrite all Min and Max numbers with Inf & -inf
matrix(matrix == Max_matrix) = inf;
matrix(matrix == Min_matrix) = -inf;

%6th Question: replace all odd numbers in your matrix with NAN
% Hand typed: ans(rem(ans,2) == 1) = NaN;
matrix(rem(matrix,2) == 1) = NaN;
