### ploting life history vectors in sage

I'm teaching a math bio class where I need to plot a life history graph. The matrix equation is new=A*old, where A is a square matrix. I want to create a matrix of the population at each iteration (for say 10 iterations) and plot each column separately. I'm having trouble figuring it out and would appreciate some help.
