How to reduce the code (csvread, reshape, concatenate matrix)?
显示 更早的评论
Hello.
I wanna reduce the below code to use several other folders. in particular, how to read files without each reading.
1. read file in the folder
2. reshape several rows to one row
3. extracting data for the same length
4. concatenate matrix
5.Add a label at the end
clear all
close all
% read file in fold
A = csvread('bend/daria_bend_geo01.csv');
B = csvread('bend/denis_bend_geo01.csv');
C = csvread('bend/eli_bend_geo01.csv');
D = csvread('bend/ido_bend_geo01.csv');
E = csvread('bend/ira_bend_geo01.csv');
F = csvread('bend/lena_bend_geo01.csv');
G = csvread('bend/lyova_bend_geo01.csv');
H = csvread('bend/moshe_bend_geo01.csv');
I = csvread('bend/shahar_bend_geo01.csv');
% reshape several rows to one row
A=reshape(A,[],1);
B=reshape(B,[],1);
C=reshape(C,[],1);
D=reshape(D,[],1);
E=reshape(E,[],1);
F=reshape(F,[],1);
G=reshape(G,[],1);
H=reshape(H,[],1);
I=reshape(I,[],1);
% extracting data for same length
A=A(1:1568,:);
B=B(1:1568,:);
C=C(1:1568,:);
D=D(1:1568,:);
E=E(1:1568,:);
F=F(1:1568,:);
G=G(1:1568,:);
H=H(1:1568,:);
I=I(1:1568,:);
% concatenate matrix
bend = [A.';B.';C.';D.';E.';F.';G.';H.';I.']
% Add a label at the end

I would do something like this.
fileList = {'bend/daria_bend_geo01.csv','bend/daria_bend_geo01.csv',<etc>}
numberFiles = numel(fileList);
bend = [];
for nf = 1:numberFiles
thisFile{nf} = csvread(fileList{nf});
thisFile{nf}=reshape(thisFile{nf},[],1);
thisFile{nf}=thisFile{nf}(1:1568,:);
bend = [bend; thisFile{nf}.'];
end
I don't have access to MATLAB -- or your files! -- right now, so I might not have the syntax just right. But I hope you get the idea.
