how i can combine two arrays which are in same dimension

date01 % array contains date and time like this '09/01/2015 00:30:00'

size(date01) =3565 1

press % array contains values of pressure like this 5.215

size(press) =3565 1

when i try to combine this two arrays in one matrices like

prm=[date01 press]

i got

error using horzcat

Dimensions of matrices being concatenated are not consistent

i need your help plz

thank you

You cannot combine string and numeric arrays in a numeric array.

You must use a cell array:

date_01 = '09/01/2015 00:30:00';
press = 5.215;

prm = {date_01 press}

prm =

    1×2 cell array

      {'09/01/2015 00:30:00'}    {[5.2150e+000]}

This should work for your arrays as it did for these two scalars.

You can also combine them in a table.

Thanks,well i need this data in a matrix to use it after in plots or inside Matlab expressions,even with your suggestion it did not work for me.my data are in text file that contains date,time,and values...i'm really stuck in this pblm....the date and time is a serious issue for me

use vertcat

[bishop Rab]

did not work,the two arrays are the same size,when i use vertcat it gives me another array with one columns

prm=vertcat(data01 press)

size(prm)= 3566 1

i'm suppose to have a size like 3565 2, i need it in two columns
