Functions to create special matrices:
The MATLAB also has various functions which create special matrices. For illustration, the zeros function generates a matrix of all zeros. Similar to rand, either one argument can be passed (that will be both the number of rows and columns), or two arguments (at first the number of rows and then the number of columns).
>> zeros(3)
ans =
0 0 0
>> zeros(2,4)
0 0 0 0
Program of built-in factorial function: Calling this function yields similar result as the built-in factorial function: >> fact(5) ans = 120 >> factorial(

Strcat function - Concatenation : The strcat function, though, will eliminate the trailing blanks from strings before concatenating. Note that in these illustrations, the trail
bar and barh functions: For a matrix, the bar and barh functions will group altogether the values in each and every row. The illustration is as shown: rm = randint(2,4,[1
Write a MATLAB function [d1, u1, l1, c1, r1] = NaiveGaussArrow(d, u, l, c, r) that takes as input the 5 vectors de ned above representing A. This function performs Naive Gauss redu
Writing to Files: There are many lower level functions which can write to files. We will focus on the fprintf function that can be used to write a file and also to append to a
