SparseLab is a Matlab software package designed to find sparse solutions to systems of linear equati

function sig = MakeBumps(n)

t = (1:n) ./n;
pos = [ .1 .13 .15 .23 .25 .40 .44 .65  .76 .78 .81];
hgt = [ 4  5   3   4  5  4.2 2.1 4.3  3.1 5.1 4.2];
wth = [.005 .005 .006 .01 .01 .03 .01 .01  .005 .008 .005];
sig = zeros(size(t));
for j =1:length(pos)
    sig = sig + hgt(j)./( 1 + abs((t - pos(j))./wth(j))).^4;
