construct a vector formed by arrays of different lengths

Hi all

i want to built a vector using multiple arrays with different length. First of all with thi code

a=zeros(100000,sum(c));
for i=1:3
a(i,:)=b(i)*ones(1,c(i));
end

with this code i want to built a 3xsum( c) matrix. b has the same dimension of c but c has different lengths!! So when multiplied with b give different lengths of a. I want to join neatly the three vector a obtained; how can i do that?

Thank you for the help!!

What?

[KSSV]

what is c? in a there are 3 rows, but you initiated it with 100000 rows.

b is an array with 3 components

c is an array with 3 component which has value:[101,17,1]

i want to obatin

a1=b1-1,b1-2,b1-3,b1-4,.....b1-101

a2=b2-1,b2-2,b2-3,b2-4,.....b2-17

a3=b3-1

and then obtain a=[a1,a2,a3]

Answer 1

a=cell(3,1);
for i=1:3
a{i}=b(i)*ones(1,c(i));
end

Thank you very much KSSV!!

but you forget to join the final vector

[EldaEbrithil]

what if i want to join the cell in a single one

for i=1:3
Acell=[a(i)];
end

is this code valid for this purpose?

[EldaEbrithil]

Ok solved with this

Acell=vertcat(a{:});

[KSSV]

yes use vertcat or cell2mat.
