How to generate 2D Frequency Matrix

I have a matrix A( i x j) like this which has row=i=1400 numbers and column=j=2.

As this matrix both column vectors has repetition of no such as 1's 15 times, 2's 18 times etc. So, I want to transfer that matrix into a single matrix which will be a frequency matrix of that one.

Such as: if i think about a table then on column i divided it into (1 to 3, 3-5, 5-7) like that and row ways (1 to 5, 5-10, 10-15) and which matrix i want that should fulfill both condition in a same row at the same time and count how many times it repeats and put that on that space or location.

Suppose, If i have row ways 10 group and column ways 5 groups then my final frequency matrix will be (10 x 5)

Please If anybody help me to sort it out! It will be great help for me!
