I have a two dimensional mat file. i want to extract each row into seperate mat files ?

I have a two dimensional mat file. i want to extract each row into seperate mat files and name it accordingly. Can you pls make available a code?

It can be done...but why you want to do that? You have everything already in a single mat ile.

Answer 1

A = rand(10) ;

n = size(A,1) ;

for i = 1:n
    filename = strcat('row',num2str(i),'.mat')  ;
    Ar = A(i,:) ;
    save(filename,'Ar') ;
end

Thanks. kindly let me know how to concatenate each row if we have 3 matrices. I have already obtained seperate mat files for each row. Best

Why are you processing data in such a slow and complex way? What purpose does saving the data into separate .mat files serve?

I want to combine 3 different data sets together(Grey matter volumes+cortical thickness-L and cortical thickness-R) and do MVPA.(we can use .mat in software) Madu

@Wasna Madushanka Ediri Arachchi: sure, your question makes it clear that you want to combine data. I asked why you are splitting one .mat file into lots of separate .mat files, and then apparently loading these back into memory to perform some operations on. Unless you are reaching the limits of your memory there seems to be no point to this diversion.

I am quite new to Matlab..That is why I am using long pathways. anyway I extracted those data from original matrices and concatenated, Thanks Stephen.
