i have matrix witn n line row

mtx = [1 1 0 1;

2 0 1 1;

3 1 1 1;

4 1 1 0;

5 1 1 0 ]; % and so on (n rows )

Single line

mtx*[1 0; 0 100; 0 10; 0 1]

mtx = [1     1  0  1;
            2    0  1  1;
            3    1  1  1;
            4    1  1  0;
            5    1  1   0 ];  
            
[m,n] = size(mtx) ; 
iwant = zeros(m,2) ; 
iwant(:,1) = mtx(:,1) ; 
iwant(:,2) = mtx(:,2:end)*[100 10 1]' ;
