Zero padding/stuffing in matlab -

basicly have array this:

[1 2 3 4 5 6]

i want have array this:

[1 0 2 0 3 0 4 0 5 0 6]

so l-1 zeros in array l number of values inside array before 0 stuffing.

anyone have idea how solve in matlab?

you can try this:

a = [1 2 3 4 5 6];   b = zeros(1, 2 * length(a) - 1); b(1:2:end) = a;

this results in

b =       1     0     2     0     3     0     4     0     5     0     6

a shorter version suggested dan in comments:

b(1:2:2 * length(a) - 1) = a;
