That way in case of a larger size matrix (say 100) i will have to keep on punching in values and the coding would be lengthy and repetitive. This way i can substitute any value for rows and cols and get my matrix already filled with random entries. Now i just have to limit the appearance of the entries according to the order of the matrix. Once i have the matrix as desired then i can start using mathematical operations in them. Just an idea for a...
