On Matlab: Use both X=A\b and X=inv(A)∗b to find x,y,z. Use tic toc to time each method. Then create a general solver to solve any linear system of n equations and n unknowns of the form AX = b. Allow the user to input the n×n matrix A and n×1 column vector b. Use X = A\b to solve the system in your script and display the solution to the user. Try your solver with A = randi(50, 10), b...

This is the sequence 1,3,6,10,15 the pattern is addin 1 more than last time but what is the name for this patternThese are called the triangular numbers The sequence is 1 3=1+2 6=1+2+3 10=1+2+3+4 15=1+2+3+4+5 You can also observe this pattern x _________ x xx __________ x xx xxx __________ x xx xxx xxxx to see why they're called triangular numbers. I think the Pythagoreans (around 700 B.C.E.) were the ones who gave them this name. I do know the...
