3d barplots are a common way to display sensitvity/elasticity matrices in
stage-structured demography.  Here's a few other options from Caswell's Matrix
population models book (2001) - I definitely  prefer 3d barcharts to these
alternatives.


heatmap(log10(A[3:1,]), Rowv = NA,  Colv = NA, scale="none")

plot(log10(c(A)), type="s")
