How to add classes number to a mat file containing feature vector of each image in a row, lets say 25 images therefore matfile having total 25 rows?

i am writing a code to classify 5 classes, each class have 10 images.

1. i am first extracting their feature vectors and saving them in a mat file.

2. i am saving them in row wise manner each image feature vector occupy one row, therefore there are total 5*10= 50 rows of feature vectors indicating each image (total 50 images).

3. as i have 5 classes, i want to add a class number with each feature vector. For example first 10 images belongs to class 1, next 10 images belongs to class 2 and then next 10 images belongs to class 3 and so on... the format would be like below:

class FeatureVector

1 #some value

1 #some value

1 #some value

1 #some value

1 #some value

1 #some value

1 #some value

1 #some value

1 #some value

1 #some value

2 #some value (below would be 9 more classes of 2 and after that 10 classes belongs to 3 and so on)

how can i do that???

Use save() to save variables into a .mat file.
