The Pascals triangle can be displayed as elements in a lowertriangular matrix as shown below for 6 rows of Pascal's triangular matrix. Write a MATLAB program that creates a n n matrix that displays n rows of Pascals triangle. The program must prompt the user to enter the number n of rows in the lower triangular matrix and then create the matrix. (One way to calculate the value of the elements in the lower portion of the matrix is 1 0 0 0 0 0 110 0 0 0 1 2 1 0 0 0 "ij (i-1)! U-1)!(i-j)! 133 1 0 0 146 410 1 5 10 10 5 1 Use the program to create 4 and 7 rows Pascal's triangles. You can use the built-in function factorial () in MATLAB. Only the Pascals triangular matrix (PT) must be displayed in the Command Window. Do Not Use disp or fprintf in your program
