combining/concatenation mat files

Hi,

i have 4 mat files in the array format(these files are outputs from a simulink model). the variables are the same in all 4 files. time is one of them.

the time sequence in all the 4 files is different (file A is from 1-250 sec, file B is from 251-500 sec.....file D from 750-1000 sec)

I want to merge these files so as to form a new file with time from 1-1000 sec

Any idea how to do it???

[i looked at other solutions on this forum & it didn't work. in my case although i have 250x3 array (time voltage and current), the variable is defined as 'sample1' i.e one variable name for 3 values]

 new_var=[];
 load file1
 new_var=[new_var;var]
 load file2
 new_var=[new_var;var]
 load file3
 new_var=[new_var;var]
 load file4
 new_var=[new_var;var]
 save new_file nw_var

% var is the name of your array

thanx Azzi but this gives me a file with data written side by side i.e i get a file with 12 column...how do i merge them one below the other???

[Azzi Abdelmalek]

there is no 16 colums, it still 3 because I'am using a vertical concatenation. check the variable new_var

Azzi, i just tried this and it worked........

X=[fileA,fileB];

Nota: En este caso la variable en los archivos es: VarA

1- Asignamos nuestros ".mat" a una variable

c1=load('file_1.mat')

c2=load('file_2.mat')

c3=load('file_3.mat')

2- Para concatenar se hace de la siguiente manera:

ctotal=[c1.VarA ; c2.VarA ; c3.VarA]
