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 you ask 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.

```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

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;```

``` A = rand(1,50);
B = rand(1,50);
C = rand(1,50);
D = rand(1,50);```
` E = [A;B;C;D];`

Thanks. How I can add one "tittle" line to 4x50 matrix so it will be 5x50 matrix? The line should be added to first line of the matrix.
