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
