The Pascal's triangle can be displayed as elements in a lower-triangular 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 Pascal's 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 (j-1)(i-j)! 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 Pascal's triangular matrix (PT) must be displayed in the Command Window. Do Not Use disp or fprintf in your program
