I have three Mat files namely '2sn0dB.mat', '3sn0dB.mat' and '4sn0dB.mat'. All of them have array 0f size 100 x 1 and having same name 'one' but having different data. I want to replace the data of 'one' in 3sn0.mat and data of 'one' in 4sn0.mat but don't want to change data of 'one' in 2sn0.mat. I want to replace the data of both 'one' of 3sn0.mat and 4sn0.mat like the following:

I want to add 0.50 to the one of 2sn0.mat file such that one of 2sn0.mat is retained but replace the 'one' of 3sn0.mat with those new values.

Likewise I want to add 0.60 to the newly formed array 'one' of 3sn0.mat such that it is retained but replace the 'one' of 4sn0.mat with these recent new values.

All the three mat files are in the attachments.

在 MATLAB Online 中打开

%if its possible try to convert the variables to a struct then perform the
%calculations
var1 = load('2sn0dB.mat');
var2 = load('3sn0dB.mat');
var3 = load('4sn0dB.mat');
var2.one = var1.one + 0.5; %add 0.50 to the one of 2sn0.mat
var3.one = var2.one + 0.6; %add 0.60 to the newly formed array 'one' of 3sn0.mat
save('2sn0dB','-struct','var1');
save('3sn0dB','-struct','var2');
save('4sn0dB','-struct','var3');
