Arrange the pseudocode for linear algebraic equation A = [1,1,1,1], b = [3:5] in the correct sequence.
Instruction: Select a number to rank each step in the process.
Rank the options below.
If rank (A) # number of unknowns, use the rrf command to display infinite solutions.
If the rank of A = rank of [A b], check if rank (A) = the number of unknowns.
Stop the program.
If the rank of A# rank of [A b], display "no solution exists."
If rank (A) = number of unknowns, compute Alb to display a unique solution.
