Dear all,
I have two arrays A and B consisting of floating point numbers. The size of array A is [104,1] and B is [641,1]. I want to compare each element of A with every element of B.
[A]=[0
2.527947992282320e-04
1.809924379782077e-04
....
]
[B]=[0
0.005
0.010
0.015
.....
]
Kindly help me.
Thanks in advance.

What does "compare" mean to you? Do you want to check for "equality"? Do you want to know which is greater or lesser? Do you want to know the distance (difference) between corresponding (or all) elements from each other? Please define "compare".

A-B'
will generate a 104x641 matrix where each row is a value of A minus each individual value of B.
The ' operator takes the transpose of the vector B, allowing you to use implicit expansion. This will only work with later versions of MATLAB I believe.
