conversion

how can we convert scalar to vector

Answer 1

[Paulo Silva]

In MATLAB a "scalar" is a vector with just one element, for example [1] is the same as 1

here's a sneaky way to separate all the digits of a scalar into columns of a vector

nc=1010; %my scalar value 
nv=num2str(n)-'0' %my vector

Answer 2

[Walter Roberson]

If S is your scalar, you can use any of the following:

reshape(S,1,[])

reshape(S,[],1)

S(:)

S.'

S(end) = S;

kron(S,1)

full(sparse(S))

Answer 3

[Oleg Komarov]

I think he intends to repmat the scalar.

Considering the other active questions by the user, I doubt that myself.
