How do I create dataset for 24 variables with 150 observations (150 x 24 matrix) belonging to 5 classes (in the 25th column ) ? I need to create variable and class labels. I have tried to save the matrix (150x24)as .dat file but need help to create labels within the file. Please help!

Hi,
You can split your dat file into 2:
150 x 24 as a data.csv
150 x 1 as the labels.csv
data = csvread('data.csv'); % Read a 2 D datafile 150 x 24
labels = csvread('labels.csv'); % Read a 1 D labels 150 x 1
a = prdataset(data,labels); % Command to create PR Datasets
a = setprior(a,0); % Reset class prior probabilities of dataset
a(isnan(a)) = 0; % Ensure there is no 'not a number'
