Dear matlabians
I have a cell variable z = (hello1 hello2 hello3) another cell variable y = (bye1 bye2 bye3) and a double x = (1;2;3 , 4;5;6 , 7;8;9)
how i can I concatenate them in a 5x3 vector
v = (hello1;bye1;1;2;3 , hello2;bye2;4;5;6 , hello3;bye3;7;8;9)
thank you

This makes the 5x3 that you requested.
c1 = {'hello' 'world' 'Happy Tuesday'};
c2 = {'Need' 'coffee' 'now'};
m1 = magic(3);
C = vertcat(c1,c2,num2cell(m1));
To make a 3x5 use;
C = horzcat(c1',c2',num2cell(m1));

z = {'hello1','hello2','hello3'};
y = {'bye1','bye2','bye3'};
x = reshape(1:9,3,3);
v = [ z ; y ; num2cell(x) ]

Here is one way. I have tried to stick somewhat close to the non-MATLAB notation that you used in your question, but still have working code:
z = {'hello1','hello2','hello3'};
y = {'bye1','bye2','bye3'};
x = [1,2,3;4,5,6;7,8,9];
v = [z',y',num2cell(x)]
The key concept that you need is the use of num2cell() to convert the numerical matrix into a cell array, so that it can be mixed with the strings.

Thank you so much people for all this answers it work perfectly. I have been programming first time with matlab 2 months now and I have made to fuctions and 1000 lines of code. But i still don't get all the variables that you could have in matlab
Do you have any good tutorial that I could read?
thanks
