I have four 1x50 matrices and I want to save them to one 4x50 matrix. How can I do this?

Accepted answer

for k=1:50 title{k}=sprintf('title%d',k) end a=rand(1,50); b=rand(1,50); c=rand(1,50); d=rand(1,50); M=[title;num2cell(a);num2cell(b);num2cell(c);num2cell(d)]

It´s not working.

for k=1:50 title{k}=sprintf('title%d',k) end a=rand(1,50); b=rand(1,50); c=rand(1,50); d=rand(1,50); M=[title;num2cell(a);num2cell(b);num2cell(c);num2cell(d)] ??? Cell contents assignment to a non-cell array object.

Try again, but before, type: `clear`

clear for k=1:50 titre{k}=sprintf('title%d',k) end a=rand(1,50); b=rand(1,50); c=rand(1,50); d=rand(1,50); M=[titre;num2cell(a);num2cell(b);num2cell(c);num2cell(d)]

I've also changed the variable **title** which is reserved to ploting functions

Answer by Youssef KHMOU on 5 Feb 2013

Suppose your matrices are A,B,C,D all with size 1x50 :

M=zeros(4,50); M(1,:)=A; M(2,:)=B; M(3,:)=C; M(4,:)=D;

Answer by Ryan Livingston on 5 Feb 2013

A = rand(1,50); B = rand(1,50); C = rand(1,50); D = rand(1,50);

E = [A;B;C;D];

You deleted the content of all the 4 questions that you asked, after people spent time and energy answering/commenting them, why?

@Teemu: I strongly suggest, that

youask the admins to restore your question. Otherwise there is the chance, that the contributors will ignore your questions in the future, because they could assume, that you are not serious. You find the address at the bottom of this page or you can ask randy Souza. Thanks.
