# Find minimum among matrices with different sizes

Hello,
I have two matrices: A=[2 8 4; 7 3 9] and B=[1 3 5]. I want to compare A and B for finding the minimum values such that the first row of A will be compared with the first row of B. Moreover, the rows of A exceeding the size of B will be not compared.
Thus, the comparison should generate a matrix C with the same sizes of A, that is: C=[1 3 4;7 3 9].
Thanks,
Best

Your statements contradict each other, but I guess this is what you want to obtain
A=[2 8 4; 7 3 9];
B=[1 3 5];
C=min(A,B)
C = 2×3
1 3 4 1 3 5

A=[2 8 4; 7 3 9];
B=[1 3 5];
%method 1
%comparing and then adding the remaining rows of A
C1=[min(A(1,:),B);A(2,:)]
C1 = 2×3
1 3 4 7 3 9
%method 2
%assinging and then comparing
C2=A;
C2(1,:)=min(C2(1,:),B)
C2 = 2×3
1 3 4 7 3 9
%method 3
%modifying B and then comparing
B1=[B;Inf*B];
C3=min(A,B1)
C3 = 2×3
1 3 4 7 3 9
