If I have 3 matrices for example
A = [10;26;30];
B = [12;25;35];
C = [15;29;9];
How can I compare among them to find each matrix that have the minimum value compared to other matrices to get matrices in this form
Anew = [1;0;0];
Bnew=[0;1;0];
Cnew=[0;0;1];
Thanks in advance

Ran in:
A = [10;26;30];
B = [12;25;35];
C = [15;29;9];
M = [A B C];
Mnew = M == min(M,[],2)
Mnew = 3×3 logical array
1 0 0 0 1 0 0 0 1

That's what min does in this case.
A = [10;0;0;26;0;0;30];
B = [12;0;0;25;0;0;35];
C = [15;0;0;29;0;0;9];
M = [A B C];
Mnew = M == min(M,[],2) & M ~= 0
Mnew = 7×3 logical array
1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 1
