How to merge two mat files

Hi! I have a problem with merging two .mat files into one. My mat files have 89 columns and about 70k verses. The thing is I need one big .mat file. Can anyone help me with this one?

A mat file doesn't contain columns but variables. If you mean your two mat files contains a variable 'd' for example, that is nx89, then you need to load your two variables from your two mat files

a1=load('file1.mat')
f1=fieldnames(a1)
a2=load('file2.mat')
f2=fieldnames(a2);
v=[a1.(f1{1});a2.(f2{1})]
save new_file v

+1 Nice example of loading into variables.

@ Azzi Abdelmalek, what it could be if each .mat file contains 50x19 feature elements?
