Matrix Division: Getting all 1s for my end result

Hey guys,

I am trying to do a matrix division by using the A./B function for a 2 large identical sized matrix. However, the end result is a same sized matrix with all 1s, despite both matrix A and matrix A having different values.

I tried creating a 2 small matrix to try out the division, and it works. But it doesn't work for my actual matrix.

Can anyone tell me what is going on?

what is your matrix size

[Guan Zhao]

Around 368x512. May get bigger depending on project requirement.

Show us the output of "whos A B"

 Name             Size              Bytes  Class    Attributes

B              456x744            339264  uint8              
A              456x744            339264  uint8

See my answer below. You need to convert A and B to floating point type (they are currently integer type uint8) in order to do floating point math with them.

See if this makes a difference

 double(A)./double(B)

THANK YOU SO MUCH!
