using Repmat function , obtain repeated specific values

z =[ 93   691   275   142     3    12]
    n=6
    for i=1:n
    a=[1:n]'
  b(i)=repmat(a(i),z(i),1)
    end

I want to obtain repeated values of a in the matrix b but a(1) should be repeated in z(1) times, and a(2) should be repeated z(2) times. Above code just gived this:

b =

6

Use repelem.

a = [1 2 3 4]

a = 1×4

1 2 3 4

b = a.^2

b = 1×4

1 4 9 16

c = repelem(b, a)

c = 1×10

1 4 4 9 9 9 16 16 16 16
