I have two arrays. A is 46x46; B is 45x45.

I want to check if the first 45 rows and 45 columns in A are equal to the 45x45 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.

Did you try

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

just to expand on this a bit the A(1:45,1:45) is the A(specified row to another specified row,specified to another specified col)
