MATLAB: Equality of an array

Question

I have two arrays. A is 46×46; B is 45×45.

I want to check if the first 45 rows and 45 columns in A are equal to the 45×45 B array.

I know to use

tf = is equal(A,B)

but don't know how to incorporate the above parameters into the isequal command.

Answer 1

Did you try

isequal(A(1:45,1:45),B)
