I am submitting my Computational science and engineering assignment #3 based on SVD/PCA.The zip file contains matlab codes of Exercise no:1 and Exercise no:3 as program_1.m and program_3.m files respectively. I have made a separate reports for the above said two exercises as Report_problem1 and Report_problem3, both in pdf format. Please find the attached zip file.
