# THIS IS A FAILED ATTEMPT TO MAKE THE BOOTSTRAP LOOP OF PWY IN FORTRAR
# Parzen, Wei and Ying's bootstrap with sparse fn fitting
# subroutine pwy(m,n,k,m5,n2,a,c,b,t,toler,ift,x,e,s, wa,wb)
# Calling sequence is just like that of srqfn.f except that
# 
#	a is now a (n+1) by p design matrix
#	c is now a n+1 vector
#	wu on input is the matrix of simulated gradient vectors
#		on output is the p by k solution matrix
#	y as in srqfn on input is the initial condition of dual
#	k is the column dimension of y, this is only added argument
