PLEASE SOLVE THIS MATLAB CODE !!

1- A cubic curve has the following BFs (blending functions), where a, b, and care constants: L. =-4at, L, = ar?, L, = br?, L, --c. Find its basis matrix and write a Matlab code to solve this problem Start with the following equation LET.B Note: For a cubic curve, L = [ L L L Ls 1-[11 X12 X22 X24 Let B- X21 X1 X41 X2 X 33 X4 Xe 2. Find the BFs of a quadratic spline having sub-division ratio k =0.8. Write a Matlab code to solve and plot this problem. Start with the following equation - 1 1 0 L(t)=T-B=[ 111 1 0 k 1 k 1
