Hello everyone! I have problem at line 8 and it states Wrong input format at line 1. Hope you could help me thank you! Godbless

Here is my code:

SPECTF = csvread('ThesisDataW1v3.csv');
labels = SPECTF(:,1);
features = SPECTF(:,2:end);
features_sparse = sparse(features);
libsvmwrite('ThesisDataW1v3SPARSE.csv', labels, features_sparse);
clear all;clc

[label, features] = libsvmread('ThesisDataW1v3.csv');
[N,D] = size(features);
labelList = unique(label(:));
NClass = length(labelList);

And attach also is my data that I want to train(Numbers 1 and 3 there specefies my two labels):

[Rik]

I would also argue against the use of clear all, if you want to use that at all you should use clearvars.

You use libsvmwrite() to carefully write out data with proper labels and features, but then you use libsvmread() to read in the original data rather than the label + feature data that you just wrote out.
