Window Design by Linear Programming

This section, based on a class project by EE graduate student Tatsuki Kashitani, illustrates the use of linprog in Matlab for designing variations on the Chebyshev window (§3.10). In addition, some comparisons between standard linear programming and the Remez exchange algorithm (firpm) are noted. For Matlab source files, etc., see
