Create matrix

Create a matrix in Matlab

% create 2x5 matrix of zeros

X = zeros(2,5)

0 0 0 0 0

% create matrix of ones

X = ones(2,5)

1 1 1 1 1

% create matrix of any repeated number (using ones or repmat)

X = 3 * ones(2,5)

3 3 3 3 3

X = repmat(3,[2,5])

3 3 3 3 3

% create matrix of NaN's

X = nan(2,5)

NaN NaN NaN NaN NaN

% create matrix of random numbers (Normally Gaussian distributed)

-0.0068 -0.7697 -0.2256 -1.0891 0.5525

1.5326 0.3714 1.1174 0.0326 1.1006

% create a vector and matrix of increasing numbers

Z = 1:10

1 2 3 4 5 6 7 8 9 10

X = reshape( Z, 5, 2)'

1 2 3 4 5

6 7 8 9 10

% create string and cell array of identical/repeated text

T = repmat("mytext",[2,5]) % string array

"mytext" "mytext" "mytext" "mytext" "mytext"

T = repmat({'mytext'},[2,5]) % cell array

{'mytext'} {'mytext'} {'mytext'} {'mytext'} {'mytext'}
