Give an example of a 2x2 matrix of numbers that represent the changes in the size of a predator-prey relationship. Then, conduct an eignvalue/eigenvector analysis of the matrix. Determine the long-term scaling factor for your populations and the long-term distribution of the predators to prey.

Then, compute trajectories for several different starting values of predators and prey. Use eigenvectors to simplify the computation of these trajectories.

Given the matrix A (2x2 matrix taking the first two column vectors from the input file), compute the followings. Λ: the diagonal matrix whose diagonal elements are the corresponding eignevalues Λii = λi for i=1,2 R: the 2x2 matrix whose ith column vector is the eigenvector corresponding to λi for i=1,2 RΛRT: the matrix compositions 1/0: the comparison between A and RΛRT (is A= RΛRT?) Your output should have seven lines where the first two lines correspond to the 2x2...

Write a program which reads the matrix A (2x2 matrix taking the first two column vectors from the input file) and the vector b (the third column vector) and solve for x in Ax=b for general A. If there is a unique solution, your output should be a 2x2 matrix with two lines and two numbers per line. The output should contain numbers with up to four significant digits. If the system is unsolvable or inconsistent, then your output should...
