i need octave plot and solution

i need a solution and an octave plot

lets assume the ID is 19-0351

Based on your student ID 19-0351 (ab-cdef) Given is the data: x = 0:10 y = a sin(ex), incase a or e are equal to use other numbers from your ID. Generate a coarse sine curve and interpolate over a finer abscissa, xt = 0:0.25:10 a) Use linear interpolation. Make a screenshot of your values for yi. b) Use spline interpolation. Make a screenshot of your values for yi. c) Plot the original points, the linear interpolation result, and the spline interpolation result in one plot. Provide a legend for the plot. Question 1: Gauss elimination and LU Factorization Based on your student ID 19-0351 (ab-cdef) ax: + dxz + exz = f a) Create 3 equations based on your team's student ID. Use Octave and gauss elimination to solve them. Make a screenshot of the code and the result. di e fi b) Create matrix A = d, e, f use Octave to find the upper triangular matrix U and a dzez 13 permuted lower triangular matrix L. Make a screenshot of the code and the result
