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

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

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]
