How to Create/Modify for matrices or matrix

K=5

matA= [1 2 ..4 K]

matB=[matA matA matA matA matA]

matB=[1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5]

How to operate this equation matB?

Answer 1

[Arif Hoq]

try this:

K=5

K = 5

matA=1:K;
% matB=[matA matA matA matA matA]
% matB=[1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5]
matB=repmat(matA,size(matA,1),numel(matA))

matB = 1×25

1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5

Answer 2

[Les Beckham]

K=5;
matA = 1:K

matA = 1×5

1 2 3 4 5

matB = repmat(matA, 1, K)

matB = 1×25

1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5
