if we want a matrix
A=[7x3] such that we iterate 100 times and its values chnage from 1 to 3 randomly on each iteration e.g
A=[1 1 1
2 1 3
1 2 1
3 3 2
3 1 2
1 1 1
2 1 3]
and in next iteration it changes again

Just use randi:
for k = 1:100
A = randi([1,3],7,3)
end

thanks but how this works? if I simply use A = randi([1,3],7,3) then only one matrix shows. where is k in it to iterate?

"how this works": it generates a new random matrix in a loop, giving exactly what you requested.
"where is k in it to iterate?" I do not understand the question. The loop variable k is not used because it is not required to generate a new random matrix.
