How to create a function of matrix with integer(from 1 to infinite) that can be arranged by row and column

for example, if m=2, n=3 then the matrix become [1 2,3 4,5,6]' if m=4 n=4 it is [1 2 3 4,5 6 7 8,9 10 11 12,13 14 15 16]' I know I should use loop, but where should I start it? i think i may need some help here...it asks one output and two inputs.

"from 1 to infinite"

Does your computer have enough memory to store an array with an infinite number of elements?

Depending on the orientation you are after, either:

reshape(1:m*n,m,n)

or

reshape(1:m*n,n,m).'

what about the integer?

[Stephen23]

What integer? Your question shows two integers, m and n, both of which occur in my answer. You did not mention any other integers.

Note that you can easily put that code into an anonymous function, e.g.:

fun = @(m,n) reshape(1:m*n,m,n);

sorry, I misunderstood it. I got this one after your answer. Thank you very much!
