want a rows to split into multiple rows

A=[111111111111111111]

i want to generate A=[111111

111111

111111]

it is (3,6) matrix...I know it can be done easily through semicolon but that i dnt want because that A matrix is the output basically.

i also used reshape command but for that dimension shoud be same. i have taken just for example (3,6).actually the matrix is of (1,90) .i wangt to make it (3,30)

kindly help

X = ones(1, 90);
Y = reshape(X, 3, []);  % 2nd argument is determined automatically

% The long form:
Y = reshape(X, 3, numel(X) / 3);

I have the suspicion that they need

Y = reshape(X, [], 3).'

That is, I suspect that they want row-wise answers, first 30 into the first row, second 30 into the second row, and so on.

ya i want first 30 in first row ,second 30 in second row ,third 30 in third row

[Jan]

Y = reshape(X, 30, 3).'

A shorter example:

X = 1:12;
Y = reshape(X, [], 3).'

Y = 3×4

1 2 3 4 5 6 7 8 9 10 11 12

ok thankyou all

[Jan]

@VASUNDHARA V: A hint for future questions: You see, that 1:12 is a better example to demonstrate, what you want to achieve than "A=[111111111111111111]". Note that this is not even a vector, but a huge scalar.

thankyou sir

I don't see why reshape() wouldn't work

A = ones(1,90);
A = reshape(A,3,30)

A = 3×30

1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
