Adding string to matrix elements

Hello,

How can I add strings to matrix elements? For example I want to add strings {'A= ' 'B=' 'C=' 'D='} to a matrix Nx4, [i(:) X(:) Y(:) Z(:)].

Matrix with elements:

              1       19.632   0.00094518      0.99995
              2       23.795    0.0014097      0.99994
              3       28.334   7.4669e-05            1
              4        3.012    0.0010539      0.99965
              5       14.704   0.00065175      0.99996

to become:

              A=1       B=19.632   C=0.00094518      D=0.99995
              A=2       B=23.795    C=0.0014097      D=0.99994
              A=3       B=28.334   C=7.4669e-05            D=1
              A=4        B=3.012    C=0.0010539      D=0.99965
              A=5       B=14.704   C=0.00065175      D=0.99996

Thank you.

Use strcat.

B=string(A);
C={'A=','B=','C=','D='};
for i=1:size(A,2)
    D(:,i)=strcat(C{i},B(:,i));
end
