To compare to matrices element by element

i have matrix A= [ 1 2 2 , 4 5 6] and matrix B = [ 1 2 3 , 2 3 4 ] . want to caompare element by element martix operators and any one element or all element in A if lessthan B should return matrix A is lesser .

[Torsten]

if A <= B

disp('A is less or equal B')

end

Hello!

I understand you are trying to compare two matrices element by element and return "matrix A is lesser" if any element in A is lesser than its corresponding element in B.

One of the ways to do this is to create a matrix C containing the maximum of A and B (element by element) and then checking if this new matrix is same as A or not.

C = max(A,B); %contains the max value out of A and B at each index
isequal(A,C); %returns true if A and C are equal else false

You can add an if condition that returns "matrix A is lesser" when isequal() evaluates to true.

Hi thank you.

can you help me with function. for eg isqual returns True it should execute a function .

if returns False it should execute other function

if isequal(A, C)
  one_function()
else
  different_function()
end

you can compare matrix A and B directly using typical comparing operators

A<B

if the question is if there is any element of A smaller than the corresponding element in B, you can use e.g.

any(A<B,'all')
