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

function A = MakeMatrix(n, p, type)
% MakeMatrix: creates various types of test matrices
% Usage
%	A = MakeMatrix(n, p, type)
%   A = MakeMatrix(d, n, type)
% Input
%	n           number of rows
%	p           number of columns
%	type        one of: USE (Uniform Spherical Ensemble), fourier, hadamard,
%	            randomortho, randomshperical, uniformrandomprojection.
%                       
% Outputs
%	 A          nxp test matrix
%
