how to construct the parity check matrix for LDPC codes

1．熟悉matlab基础操作。 2．能够用Lagrange插值, Newton插值法对函数表进行一次、二次、三次插值，体会各种插值方法不同的特点。 (A. Familiar with matlab underlying operating. Two. With Lagrange interpolation, Newton interpolation function table once, quadratic, cubic interpolation, and appreciate the different characteristics of the various interpolation methods.)
