MATLAB: How can i achieve this “linspace” problem

for looplinspacematricesmatrixmatrix manipulation

I should create 3 matrix (named as "d") with using linspace, but i can not use linspace command in for loop as at the code box. What is the reason of this problem?
Thanks,
kk=[8 10 12]
for j=1:numel(kk)
  d(j)=linspace(0,50,kk(j))
  end
alternatively;
for r=1:1:numel(kk)
  for u=1:1:numel(kk)
  dd(r,:)=linspace(0,50,kk(u))
  end
end
I want to create 3 dd matrixes with using linspace by 8,10 and 12 values.

It is not possible to put multiple elements into one element of a numeric array. Use a cell array:
vec = [8,10,12];
d = cell(size(vec));
for k = 1:numel(vec)
    d{k} = linspace(0,50,vec(k));
end
giving:
>> d{:}
