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 (e value of the elements in the lower portion of the matrix is 1 0 0 0 0 0] 11 0 0 0 0 = ij (j-1)!(i-j)! 15101051 Use the program to create 4 and 7 rows Pascal's triangles. You can use the buil factorial) in MATLAB. the Command Window. Do Not Use disp or fprintf in your program. t-in function Only the Pascal's triangular matrix (PT) must be displayed in
