How do I prevent my code from printing the ans statements?

for k=2,3,4,5
X = randi([0,1],[k,4])
end

ans = 3

ans = 4

ans = 5

X = 2×4

0 1 1 0 1 0 0 1

% this is equivalent to what you wrote
for k = 2 % these are all individual statements
    3
    4
    5
    X = randi([0,1],[k,4])
end

ans = 3

ans = 4

ans = 5

X = 2×4

0 0 1 0 0 0 1 0

for k = [2,3,4,5] % this is one statement
    X = randi([0,1],[k,4])
end

X = 2×4

0 0 0 0 1 0 0 0

X = 3×4

0 1 0 1 1 0 1 1 1 0 0 1

X = 4×4

0 0 1 0 0 1 0 0 0 1 0 0 0 1 0 1

X = 5×4

1 0 1 0 0 1 1 0 0 0 0 1 0 1 0 0 0 1 0 0

Oh ok, however I only want it to print one matrix. Not all 4, just randomly choose k x 4

"Not all 4, just randomly choose k x 4"

But your code does not "randomly choose" any matrix. Is that a feature that you wish to add?

If you only want one matrix, why are you generating four of them?

[DGM]

You mean like this?

X = randi([0,1],[randi([2 5],1),4]) % ?

X = 3×4

1 1 1 0 0 0 0 0 1 0 1 1

I need to write a script that prints a matrix that is k rows x 4 columns. K must be an integer 2-5. K should be chosen randomly. The matrix must contain only zeros and ones that are randomly generated. What you just commented works for the output, but I need to format it in such a way that K is assigned 2-5 then imported into the matrix call.

[Stephen23]

If you only need one matrix then get rid of the FOR loop, and define K using RANDI.

X = randi([0,1],[randi([2 5],1),4])

X = 4×4

0 1 0 0 1 1 0 1 0 0 0 0 1 1 0 1

Thanks this works!
