I want to concatenate 2 arrays of same dimension. And I want to add a blank space in between. When I use ' ', the dimension changes to nx2 while I want that the dimension should remain as nx1. Is there any way out to do this? Any help is welcome !!!!

E.g.: 2 arrays are of dimension n x 1. I want to concatenate them with a blank space. And, after that also I want that the dimension should be n x 1 and not n x 2.

Thanks again !!!!

Please, Swasti, give an explicite example. E.g.

Input:

C1 = {'26-Jun-2993'; '23-Dec-1998'}

C2 = {'17:23:45', '18:10:17'}

Output:

C3 = {'26-Jun-2993 17:23:45'; '23-Dec-1998 18:10:17'}

???

There are several possible types of "an array containing date and time".

The example is perfect for my case.

Perhaps you are looking for:

strcat(C1, {' '}, C2)

strcat(C1(:), {' '}, C2(:))

Then why is my answer not correct? What do you mean concatenate horizontally? Do you mean a row vector? Then just transpose the result.

Swasti Khuntia 2012-6-18

In my case, I have a Nx1 date vector and Nx1 time vector. I want to concatenate the two vectors so that the date and time vector is represented in a single vector (i.e., side by side with a blank space). When I try to use ' ' (blank space), the string concatenates no doubt but there are two columns. I hope you get my query.
