Dear Roopa,

Matlab has a special command for reading Excel sheets, using which you can retrieve the numerical values into a matrix as follows:

matrix=xlsread('GLCM_features.xlsx');

(I here assume you have the file in the working directory, but you can of course augment the string with the appropriate directory path.). You can then manipulate or plot various values in this matrix. 

Cheers,

Pekko
